Sunspots made a solid reappearance over this reporting week (June
4-10) with average daily sunspot number rising from 3.3 to 14. As
expected, solar flux also increased, and the average daily 10.7 cm
solar flux rose from 69.6 to 71.3.
With renewed solar activity, so many radio amateurs staying home,
and the increasing popularity of new weak signal modes, there is a
lot happening on the air in amateur radio today.
Average daily planetary A index went from 6 to 5.1, while average
daily middle latitude A index changed from 5.7 to 6.1.
The outlook for the next 45 days has solar flux at 72 on June 12-14,
70 on June 15-16, 68 on June 17-24, 70 on June 25-26, 72 on June 27
through July 11, 70 on July 12-13, 68 on July 14-21, 70 on July
22-23, and 72 on July 24-26.

and 12 on July 4-5, and 5 on July 6-26.
