Propagation News – 9 May 2021

The Sun was devoid of sunspots last week, which saw the solar flux index plummet to 70 – pretty much what it is around sunspot minimum. The good news is that an active region is rotating into view. Region 2817 is currently just on the Sun’s eastern limb as this report is being prepared and should be visible by the …

The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Our sun seems to have fallen back into a very quiet phase, far different from the way it looked in November 2020. That was 6 months ago, and we assumed that since we were emerging from a solar minimum, by now we would be seeing much more solar activity. It hasn’t happened. More recently, sunspots …

Propagation News – 2 May 2021

Last week was characterised by relatively low sunspot numbers, but reasonably settled geomagnetic conditions. The solar flux index never rose above 80 all week, despite a large cluster of sunspots. This cluster, composed of regions 2818, 2820 and 2821, were responsible for some C-class solar flare activity, but never really grew into anything. By the time you read or hear …

Propagation News – 25 April 2021

Last week was marked by solar flares, perhaps giving us a taste of things to come as the solar cycle progresses. The Kp index hit four on Monday after the weekend’s high of five. But luckily things then calmed down and we have been seeing the Kp index down to two overall. There was even one three-hour period where it …
