Propagation News – 12 May 2019

Sunspot group 2740 has now returned and is emitting a lot of radio noise. Solarweather.com reports large bursts have been recorded on 20 and 25MHz. The bursts sound like waves breaking on the shore and are caused by beams of electrons accelerated by explosions in the sunspot’s magnetic canopy. As the electrons slice through the Sun’s atmosphere, they generate a …

The K7RA Solar Update

We saw zero sunspots from April 21 through May 2, but on May 3 sunspots returned. Average daily sunspot number rose from zero last week to 16.1 this week, and average daily solar flux increased as well, from 67.5 to 73.5. Both the average middle latitude and planetary A index this week were 6.6, and last week those numbers were …

Meanwhile, a lack of sunspots and continuing coronal hole activity means F2-layer DX is a little harder to come by. Last week’s International Marconi Day saw some reports of …
