also noted 50-MHz 2Es on Sep 2 (2000-2200) to Puerto Rico, Bermuda,
and Venezuela. rare at this time of year after a poor August of Es;
-several frequencies just below 6-m (e.g., 49.58/.63/.68/.73/.78)
noted are believed to be from Colombia/Bolivia/Argentina in on F2

Large aurora caused by the largest magnetic storm of the year on Aug
27-28 was reported visible as far south as Santa Fe, NM
----
Solar flux, after dropping below 100 for the first time since January,
rose within a week to the 170-180 range. That represents the highest
flux in a September since 1960.
----
Swiss sunspot predictions have the smoothed number for December at 117.
That's higher than the peak smoothed value for Cycle 20.
----
Another recent prediction on Cycle 21 has a peak in late 1979 of just
over 200 (sunspot number), with a 66% chance it will fall within the
160 to 250 range. That's getting into the size of the record Cycle 19.
----
With all this the fall F2 season should easily be the most active since
the 1968-1970 period. This will be maybe the best chance to catch the
BBC TV signals before they move them from low-VHF (see p. 10 Aug VUD).
With the right conditions the transcontinental MUF might get to the
50-54 MHz region (or more).
----
I have available an abstract of Texas stations in the 30-50 MHz band
from the Feb 1971 (and update Aug 1972) ITU list. It runs some 12 pages.
A lot of the police/fire can be found elsewhere, but a lot of the bus-
iness listings might not be so easily located. $2 to cover Xerox and
mailing costs. (in ascending frequencies then alphabetically by town)
Can be very useful in identifying all those KK-### calls in Texas.
