    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 ama...

    We just experienced a nearly two-week period of sunspots appearing every day. It's been quite some time since we've witnessed a continuous string of sunspot activity such as what we've experienced over the past two weeks. Back on January 24 through February 1, 2020 were nine consecutive days with sunspot activity, but to find any longer period of sunspot appearances requires a look back to May 3...

    No sunspots were observed since June 15, when the daily sunspot number was 11. This does not mean there were 11 sunspots seen, but instead it means that one sunspot group was observed containing one sunspot. The sunspot number is derived by assigning 10 points for each sunspot group, and one point for each sunspot. So, 11 is the minimum non-zero sunspot number.
    On June 8, the daily sunspot numbe...

    No sunspots this week. The pattern persists, and this surprises me. But Spaceweather.com reported a couple of weak, barely emerging spots, never numbered, and by their magnetic polarity were from new Cycle 25.
    We rely on NOAA for official sunspot numbers, and the most recent one reported was 11 on June 15. See ftp://ftp.swpc.noaa.gov/pub/indices/DSD.txt.
    Average daily solar flux over the recent r...
