Propagation News – 5 July 2020

This week saw the beginning of a new month and continued sporadic E openings. Traditionally we see a slow down in the number of sporadic E openings in July, but while we are seeing a few periods on 10m when there are no openings, they inevitably reappear. An HF F2-layer opening to Angola occurred on Wednesday, allowing amateurs to bag …

The K7RA Solar Update

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 …

Propagation News – 28 June 2020

After the recent excitement of a new Solar Cycle 25 sunspot, it seems the Sun has decided to go back to sleep. We have had zero sunspots since 16 June and the STEREO spacecraft Ahead view shows just one small bright area on the Sun, which might result in a spot in due course. Luckily, geomagnetic conditions remained quiet throughout …

The K7RA Solar Update

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 …

Propagation News – 21 June 2020

We had another week dominated by sporadic E HF contacts. Ten metres has been open daily to Europe and often until very late at night. There have been reports of USA and Japanese FT8 contacts from the UK during the day, continuing almost to midnight. By Thursday signal levels appeared to be dropping off at first but, by 1100UTC, Canada …

The K7RA Solar Update

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 …

Propagation News – 14 June 2020

Well, we’ve finally got a good Solar Cycle 25 sunspot to talk about! Region 2765 was a big one with a number of spots appearing, taking the sunspot number to 17 at one point. But by the time it had rotated into the centre of the Sun, the spot had started to decline a little. While the sunspot had little …

The K7RA Solar Update

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 …
