FYI: Solar Cycle 23 Graphs - Where are We Now
Cycle 23 started in May 1996 with the monthly SSN at 8.0 and peaked in April
2000 at 120.8. The next solar minimum will likely occur sometime in 2006 with cycle 24 peaking in 2010. See URL: http://www.dxlc.com/solar/solcycle.html -- Caveat Lector |
Thanks for this! The sun is so fickle...
Can you point us toward a website that can translate this into propagation predictions? Thanks, Bruce Jensen |
Try these:
ARRL Propagation News Letter -- ARRL Members Only -- ARLP001 Propagation de K7RA http://www.arrl.org/w1aw/prop/ Also see URL: http://www.arrl.org/tis/info/propagation.html Lots of prediction websites there Latest ARRL prop news letter sez Now for conditions over the short term, a week ago it looked like solar flux should stay above 100 over the following 10-12 days. Now the last of sunspot 715 is disappearing around the edge of the sun, and it looks like solar flux should stay around 85 with sunspot numbers below 40 over the next week. Saturday, January 8 could see some unsettled to active geomagnetic conditions, and January 13 could see unsettled conditions as well. Quiet days are expected January 10-11. see the ARRL Technical Information Service propagation page at, http://www.arrl.org/tis/info/propagation.html . Sunspot numbers for December 30 through January 5 were 34, 60, 51, 52, 43, 30 and 15 with a mean of 40.7. 10.7 cm flux was 100, 98.5, 98.9, 100, 94.2, 88 and 88, with a mean of 95.4. Estimated planetary A indices were 15, 8, 15, 33, 22, 23 and 21 with a mean of 19.6. Estimated mid-latitude A indices were 12, 5, 10, 20, 14, 16 and 11, with a mean of 12.6.

A good program
W6ELProp™ -- By Sheldon C. Shallon, W6EL - predicts ionospheric (sky-wave) propagation between any two locations on the earth on frequencies between 3 and 30 MHz. -- Caveat Lector "Caveat Lector" wrote in message news:KYADd.43137$8e5.40480@fed1read07...
