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. 73, WA5IYX
