Solar Update:
After bottoming out on April 16 at 123.4, solar flux is on the rise. Average
flux values for this week were up over 50 points, and activity is still
increasing with the return of sunspot region 9393. Solar flux is expected to
peak this weekend around 210, but a rise in geomagnetic activity due to a large
M7-class solar flare on Thursday is expected on Sunday. This flare was from
sunspot 9393, which also hurled a full halo coronal mass ejection. This sunspot
covers about half the area that it did when it was on our side of the sun last
month, but it is still quite large. Last month it produced the largest solar
flare ever recorded, which fortunately was not pointed toward earth.
On Monday an enormous prominence (a filament of cool dense gas suspended above
the sun) extended over the sun's southwestern limb. You may still be able to
view a photo from the Solar and Heliospheric Observatory at
http://spaceweather.com/images2001/23apr01/20010423_1837_eit_304_big.gif
A number of emails have arrived lately asking about some of the numbers reported
in this bulletin, so it is probably time to run the following explanation.
Amateur Radio operators who use HF generally like increased sunspots because
they correlate with better worldwide radio propagation. When there are more
sunspots, the sun puts out radiation that charges particles in the earth's
ionosphere. Radio waves bounce off of (refract from) these charged particles,
and the denser these clouds of ions, the better the HF propagation.
When the ionosphere is denser, higher frequencies will refract off it rather
than passing through to outer space. This is why every 11 years or so when this
activity is higher, 10 meters gets exciting. 10 meters is at a high enough
frequency, right near the top of the HF spectrum, that radio waves propagate
very efficiently when the sunspot count is high. Because of the shorter
wavelength, smaller antennas are very efficient on this band, so mobile stations
running low power on 10 meters can communicate world wide on a daily basis when
the sunspot cycle is at its peak. There are also seasonal variations, and 10
meters tends to be best near the spring or fall equinox. If the ionosphere is
not so dense, the Maximum Usable Frequency may be below 10 meters, and perhaps
only signals with frequencies as high as 15 meters or below will propagate.
The sunspot numbers used in this bulletin are calculated by counting the spots
on the visible solar surface and also measuring their area.
Solar flux is another value reported in this bulletin, and it is measured at an
observatory in Penticton, British Columbia using an antenna pointed toward the
sun hooked to a receiver tuned to 2.8 GHz, which is at a wavelength of 10.7 cm.
Energy detected seems to correlate somewhat with sunspots and with the density
of the ionosphere.
Other solar activity of concern to HF operators are solar flares and coronal
holes, which emit protons. Since the charged ions in the ionosphere are
negative, a blast of protons from the sun can neutralize the charge and make the
ionosphere less refractive. These waves of protons can be so intense that they
may trigger an event called a geomagnetic storm. In addition, energy from a
solar flare may energize the D-layer of the ionosphere, which absorbs radio
waves.
The Planetary A index relates to geomagnetic stability. Magnetometers around the
world are used to generate a number called
the Planetary K index.
A one-point change in the K index is quite significant. K index readings below 3
generally mean good stable conditions, and above 3 can mean high absorption of
radio waves. Each point change reflects a big change in conditions.
Every 24 hours the K index is summarized in a number called the A index. A
one-point change in the A value is not very significant. A full day with the K
index at 3 will produce an A index of 15, K of 4 means A of 27, K of 5 means A
of 48, and K of 6 means A of 80. You can find an explanation of these numbers on
the web at http://www.ngdc.noaa.gov/stp/GEOMAG/kp_ap.html.
The geomagnetic number reported here is the Planetary A index, which is a
worldwide average based on the K index readings from a number of magnetometers.
The numbers reported on WWV are the Boulder K and A index, measured in Colorado.
Generally the higher the latitude of the measuring station, the higher the K and
A indices reported. This is because the effects of geomagnetic instability tend
to concentrate toward the polar regions of the globe. You can hear the Boulder K
index updated every three hours on WWV, or by calling 303-497-3235.
For an interesting web page on the earth's magnetosphere, check http://science.nasa.gov/ssl/pad/sppb/edu/magnetosphere/bullets.html
Sunspot numbers for April 19 through 25 were 85, 103, 156, 164, 140, 175 and 182
with a mean of 143.6. 10.7 cm flux was 144.5, 180.4, 191.1, 192.5, 196.4, 193.5
and 193.9, with a mean of 184.6, and estimated planetary A indices were 7, 8, 7,
28, 21, 8 and 7 with a mean of 12.3. (K7VVV)

QRT around 0600 today. Hopefully all the hard work, effort and
expense gave some of you lot a new country! Complete 6M log and statistics
will be made available in due course. Hopefully next week.
The crew
now have a rough 70 hour +/- sail back to Gladstone. It was so rough on
the way out nobody ate solids, just soups etc, couldn't hold it down let alone
prepare a meal in the galley. The things hams do!
In addition to
logs and stats there will soon be a collection of pictures on the website to
look at;

Mellish Reef, VK9ML 2nd Update:
VK9ML will be listening for VK to take advantage of the early morning
scatter path that exists between 2000 - 2130 UTC. The ops tent is manned
from around 0500 local in the morning and the crew will be monitoring 50.105.6
and have the beacon keyer running. Signal strength peaks around 7am local
in the morning, strong enough for SSB. This is the same path as for TX0DX in
February 2000.
22/4
Mellish Reef, VK9ML Update:
Peter operating VK9ML was worked in Brisbane early this morning via
tropo scatter @ 20:25 (still 21/4 UTC date) on CW. Copy was pretty light but a
few stations got through. vk9ml on cw
It took a number of minutes for a complete 2-way exchange. Later on @
21:10 Peter was strong enough to be heard on phone
for a few minutes.

Ascension Island, ZD8VHF:
Johhny, ZD8KW, writes...
Here is the new 6 m antenna situated at the beacon now I have just installed the
new antenna with the help of lenny who gave up his value Friday afternoon to
help out Ian thanks for reminding me to switch of the beacon before I
dismantle the old antenna but you did not remind me that the new antenna had a
pl259 type fitting on it and the old antenna had a uhf type connector on it so
it just cost a trip back down the mountain to change the connector on the
end of the coax after I had carefully put together all the bit s and pieces in
the truck in order to make it a one trip up replace antenna and home again
however it took us to 8 pm (dark with a torch) almost to finally got it sorted
by the time we return to the mountain and secure and insulate the cable and tune
the antenna up.

Not to forget I forgot to put batteries in the camera so the old ones allow me
to take one picture only which is this one - above.
I will take more to send you as well in a few days I would be interested to know
if the signal has improved as well the vswr is 1,2,1 acceptable I guess will
update later let me know if this is ok the way it is mounted etc regards for
now. Johnny Clingham

Mellish Reef, VK9ML Update:
As of 21/4/01 0824 there are 720 QSOs in the
electronic log. There were many QSOs with JA that were initially logged
manually by hand. This was done in order to get the 6M station on the air
as soon as possible not having to wait for the laptops to be setup and
interfaced to the rigs. These QSOs will be added to the master log file
once the team have returned home to Brisbane.
VK9ML has worked 6 DXCC entities so far on 50MHz in the following areas:
JAPAN JA0,1,2,3,4,5,6,7,8,9 and Okinawa
KOREA DS1,5, HL1,2
HAWAII KH6

21/4
Mellish Reef, VK9ML:
The team landed on the reef at 23:21 Thursday. The nose of
the catamaran went straight up onto the beach area on the Western side of the
reef. In the first 24 hours about 1,000 contacts have been made on 6M
with JA, HL and V73. No VK, yet! About 1,000 contacts have been
made on HF as well.
21/4
Solar Update:
Solar flux and sunspot numbers have been declining, but still there is plenty
of activity to keep geomagnetic conditions active. Mean daily sunspot numbers
declined by nearly 60 points this week over last, and average solar flux was
down nearly 44 points. Sunspot numbers were down to the double instead of
triple digits this week, with Tuesday through Thursday sunspot numbers at 89,
63 and 85. Sunspot numbers were last in the double digits about a month ago.
That large sunspot that caused so much excitement a few weeks ago is now
visible again, and about to rotate into full view. Daily solar flux probably
reached a minimum on Monday at 123.4, and the latest forecast has solar flux
for Friday through Monday at 155, 165, 175 and 185. Solar flux is expected to
peak somewhere around April 27 or 28 at 230. Of course, new activity could
change this. After all, when solar flux peaked at 273 and 274 on March 27 and
28, a week earlier the best guess was that solar flux would peak around 180 on
those dates.
Last Friday a strong geomagnetic storm was triggered by an interplanetary
shock wave. This followed a couple of days of similar effects from coronal
mass ejections. Then on Sunday, one of the most powerful solar flares ever
recorded was observed, but it was near the sun's western limb, and mostly
aimed away from earth. But Gary, WB0FFI, was talking to a friend on 80
meters a little over 200 miles away in Colorado on Sunday morning when all
signals on the band
suddenly vanished. Gary reported that signals went from S9 to nothing, and all
that was left were electrical noise and the buzz of television sweep
oscillators. Gary wondered if the energy from this flare caused a sudden
expansion of the D layer, absorbing radio waves, and I think he is probably
right. The X14 class flare happened at 1350z, right during Gary's weekly
1330-1430z sked.
Another interplanetary shock wave struck earth on Tuesday. This has been quite
a week for auroras. The most disturbed day this week was Wednesday, when the
planetary A index was 50 and the planetary K index reached 7 over two periods.
This came one week after another severe disturbance, when the planetary A
index was 60 and the high latitude College A index was 100.
Sunspot numbers for April 12 through 18 were 159, 138, 149, 100, 107, 89 and
63 with a mean of 115. 10.7 cm flux was 149, 137, 138.7, 134.2, 123.4, 126.1
and 131.8, with a mean of 134.3, and estimated planetary A indices were 38,
36, 15, 13, 7, 7 and 50 with a mean of 23.7.

Exmouth Beacon, VK6RSX:
Don, VK6HK, writes regarding an update on VK6RSX...
After some problems at the original site at Exmouth, the VK6RSX beacons on
50.304 (and 144.576) MHz have been moved to a new site at Dampier, Western
Australia (QTH OG89). The transmitters and antennas are as before (50W into an
omni).
The location is near to where VK6PA operated so successfully last cycle.
The VK Beacon Map has been updated.
VK6RSX on 50.304 is readily receivable in Perth over about 1200 Km via meteor
scatter most days.
16/4
Mellish Reef Site Survey/DXpedition, VK9ML:
Alan, VK4BKM, Peter, VK4APG, and Harris, VK4CWT, will arrive in Gladstone lunchtime
today after a seven hour drive from hometown Brisbane early this morning to meet
up with David, VK4GL and Bill Brosnan (non-amateur sailing crew member).
The transport out to the Reef is David's catamaran "Bach & Byte"
which came third on handicap in the multi-hull section of the Brisbane to
Gladstone Easter yacht race. The boat is in fine condition - no broken
masts like last year just prior to leaving for the VK9WI Willis Island
DXpedition!
The VK9ML crew will sail out of Gladstone Tuesday morning headed for Mellish
Reef. Expecting to arrive Friday +/- WX.
Peter, VK4APG, the VK9ML 6M operator will be taking along a third transceiver
an Icom IC-706 and will activate 10M if 6M is dead, and, providing there is
little interference to the main HF station that will also be operating.
Expect the 6M rig, a Kenwood TS-60, to be running in Beacon mode at times on 50.105MHz (the
CW frequency). The phone frequency will be 50.145MHz. If your rig
has dual watch - listen on these two and you can't miss!
qsl.net doesn't appear to running 100% still. Although new News
Bulletins have been FTPed to the site it is still referring to older
pages:( Hopefully Al will have all the problems sorted out and back in
shape before weeks end when VK9ML arc ups.

Malpelo Island, HK0JJH:
16 Apr ys1rr-1 (0028Z) : hk3jjh/hk0 will be in 6m tomorrow de ys1rr
Background info from SM7AED:
March 20.
Malpelo Island, HK0JJH.
Looks like Pedro, HK3JJH will be going to Malpelo with a IC-706 xcvr April
2001 and does plan some 6M activity. This will be the first time ever Malpelo
has been QRV on 6M, and perhaps a once in a 6M DXers lifetime chance to work
Malpelo on the magic band. Pedro's QTH is on the south side of Malpelo with a
large mountain between him and the states. Pedro has a clear shot to EU, South
America, Oceania and Japan. Malpelo should experience similar 6M prop. to the HC8GR beacon. He may be workable by W/VE 6M DXers via backscatter, I
worked him on Malpelo via 10M backscatter in 1999. 6M DXers who wish to
encourage Pedro to spend some time on 6M should consider sending a
contribution for his DXpedition to N4AA.

Solar Update:
High solar activity continued this week. Although the actual sunspot numbers and solar flux values have generally declined, new active areas on
the sun have rotated into Earth's view, bringing flares and coronal holes--and with them geomagnetic storms and dramatic auroral displays.
Average sunspot numbers for the week declined more than 100 points, and average solar flux was off more than 62 points. Again this week, on April
5 and 6, the 10.7 cm solar flux value had to be adjusted because the observatory in
Penticton, British Columbia was overwhelmed by energy from
solar flares. Daily values for last Thursday and Friday were flare enhanced at 398.7 and 563.5, but were adjusted downward and reported by
NOAA as 210 and 192.
As this bulletin is being written on Thursday, two clouds of charged particles are headed our way. The last is from another X-class solar
flare. This one erupted near sunspot group 9415 at 1025 UTC, and caused a radio blackout across the Atlantic Ocean, Europe, and parts of Western
Asia.
On Wednesday energy from a pair of coronal mass ejections hit Earth and triggered a severe G4-category geomagnetic storm between around 1500-1800
UTC. G4 category is severe, one step below the top G5 category, which is extreme. This may cause problems with power distribution systems, with
surges in voltage and tripping of circuit breakers. On Wednesday the planetary K index hit 8, and the planetary A index was 60. Middle latitude
A index was 69.
On the bands expect long periods of very little HF propagation, but look for auroral propagation on VHF. Current predictions call for solar flux to
decline below 150 this weekend and bottom out around 140 on Sunday. Then, it is expected to rise to 180 around April 20,
and peak around 185 after
April 23 and toward the end of the month.
Sunspot numbers for April 5 through 11 were 214, 136, 153, 188, 185, 170 and 178 with a mean of 174.9. 10.7 cm flux was 210, 192, 179.5, 169.2,
164.8, 169.7 and 159.6, with a mean of 177.8, and estimated planetary A indices were 19, 12, 16, 41, 19, 9 and 60 with a mean of 25.1.

Solar Update:
This has been another week of remarkable solar activity, with Sunspot 9393
producing more excitement. Sunspot numbers peaked on March 28 and 30 at 352
and 349, and solar flux on March 27 and 28 at 273.4 and 273.5. Total visible
sunspot area peaked on March 29 at 3940 millionths of the solar hemisphere.
This week solar flares tossed out enough energy to overwhelm the equipment
that measures 10.7 cm solar flux.
At 2300z on April 2 the flux reading was 563.1, and on April 5 the readings
were 582.5 and 398.7 at 1700 and 2000z. These flare-enhanced readings would
certainly be a new record far beyond any daily values reported for this solar
cycle, but they are discarded because they don't reflect actual 10.7 cm
energy. So for April 5, instead of a daily reading of 398.7, NOAA reported
210, probably a guess based upon declining daily readings and a more accurate
2300z reading of 207.5.
Following the new high in sunspot numbers, we have seen a number of large
solar flares and resulting aurora. On April 2 the most powerful flare in at
least 25 years erupted. Fortunately most of it was aimed away from earth. A
few days earlier on March 31 the planetary A index soared to 155 and the
planetary K index went as high as 9 during a severe geomagnetic storm. There
were incredible auroral displays, seen as far south as Mexico. See an amazing
gallery of aurora images, many from southern regions that very rarely see
aurora, at http://spaceweather.com/aurora/gallery_31mar01.html
.
Since March and the first quarter of the year are both over, it is time to
report some numbers for those periods. Average solar flux for March was 177.7.
This is an increase, as the average daily solar flux for December through
February was 173.6, 166.6 and 147.2. Average daily sunspot numbers for March
were 166.7, and for December through February were 146, 143 and 131. Quarterly
average solar flux for last year was 180.5, 182.9, 188.3 and 173.3.
For the first quarter of this year the average solar flux was 164.4. The
average daily sunspot number for the quarter just ended was 147.3, and the
quarterly sunspot averages for last year were 168.9, 190.8, 193.1 and 145.
Although this quarter really ended with quite a bang, the quarterly averages
for both solar flux and sunspots were lower than the same period a year
earlier.
Although the really active regions have now rotated off of the visible solar
disk, there are more rotating into view. Predicted solar flux for the next few
days, Friday through Monday, is 210, 210, 205 and 205. The predicted planetary
A index for those days is 15, 8, 8 and 10.
For some time now W6EL's MiniProp program for propagation prediction has been
unavailable. This is the program used to generate the occasional path
predictions shown in this bulletin. I am extremely happy to report that W6EL
has just released a new free version of his software, this time for Windows,
and you can get it at http://www.qsl.net/w6elprop/.
It works with all recent versions of Windows, including 95, 98, ME, NT and
2000. Be sure to give this a try, and send W6EL a note of thanks. It is a
great piece of software for looking at seasonal, time of day, frequency and
solar activity variables and their effects on HF communications.
Sunspot numbers for March 29 through April 4 were 315, 349, 326, 320, 223, 228
and 217 with a mean of 282.6. 10.7 cm flux was 261.7, 256.8, 245.6, 257.5,
228, 223.1 and 204.8, with a mean of 239.6, and estimated planetary A indices
were 22, 10, 155, 30, 20, 5 and 15 with a mean of 36.7. (K7VVV)

Long Path Propagation:
What a night! JAs in during most of the evening, with the
appearance of that annoying carrier on 50.110. When we hear we know
there's a path across to the Hong Kong region. Sure enough up popped
VR2XMT, VR2ZXP, VR2VXD and others from 13:00 onwards.
13:20 saw 9M6BAA audible working JA's. It was nice of Peter to swing his
beam around to work the VK's (JA's take note of this courtesy!) on CW &
Phone. 13:54 and the path still open with a QSO to Richard,
BV2DP.
Luckily the beam was sitting on 330° here at VK4CP where LU8MB was heard
calling. VK4CP, VK4KK and VK4JSR worked LU8MB 51 in FF57oc between 14:32
-14:35. He was gone less than 10 minutes later, with no other SA stations
heard.
