Propagation Forecast Bulletin 24 ARLP024
From Tad Cook, KT7H
Seattle, WA June 18, 1993
To All Radio Amateurs
Solar activity continued to decline last week. Sunspot numbers went
as low as 11, and flux went down to the low eighties. There were
almost no visible sunspots.
Solar flux will begin rising after this weekend, and should reach a
modest peak near 120 around the end of the month. This next
activity is expected from returning region 7518. Geomagnetic
activity should be mostly quiet, but there could be some upsets
around the first of July, and again around July 7.
Sunspot Numbers from June 10 through June 16 were 61, 44, 33, 24,
11, 11 and 11, with a mean of 27.9. 10.7 cm flux was 112.6, 101.8,
93.3, 86.6, 83.7, 82 and 82.3, with a mean of 91.8.
The projection for this week is from Omaha, Nebraska to Libya.
80 meters should be open from 0130z to 0400z, peaking around 0230z.
40 meters should be open from 0000z to 0530z, peaking from 0230z to
0400z. 30 meters should be open from 2300z to 0600z, peaking from
0100z to 0430z. 20 meters should be open from 2200z to 0630z, with
the best times from 0000z to 0500z. 17 meters should be open most
days from 1730z to 2300z. Due to low solar activity, 10, 12 and 15
meters do not look promising over this path.
