Propagation News – 10 January 2021

We start by welcoming in 2021, and here’s hoping that it proves to be more fruitful than 2020 in terms of HF propagation. We’ve started the New Year with zero sunspots and a solar flux index back in the mid-70s on Thursday the 7th. The STEREO Ahead spacecraft is not showing anything of note around the back of the Sun, …

The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Sunspots disappeared after January 2, so the average daily sunspot number dropped from 27.1 last week to 10 for the December 31 – January 6 reporting week. As a result, average daily solar flux declined as well, from 86.4 to 78.6. Geomagnetic indicators remain quiet, with planetary A index changing from 6.9 to 5.1, and …

The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Solar Ccle 25 is progressing normally, and with the new year, my outlook is optimistic. Solar minimum occurred just over a year ago (December 2019), and now we see very few days with no sunspots. Both of the current sunspot groups (2794 and 2795) are about to slip across the sun’s western horizon. Average daily …

The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Merry Christmas! Sunspots went missing last Friday and Saturday, but large new sunspot group 2794 appeared on Sunday, December 21, and on Wednesday, Spaceweather.com reported new sunspot group 2795 emerging over our sun’s southeastern limb. This disappearance depressed the average weekly sunspot number, which went from 17.4 last week to 10.3 this week, ending on …

Propagation News – 27 December 2020

HF conditions were not terribly good over the last week with maximum usable frequencies down in general. The best DX has been on 40m, especially around greyline times, although there has been a little winter Sporadic-E activity on 10 metres as well that has seen Italy and Spain appearing on FT8, as well as Brazil on 10m via the F2 …

Propagation News – 20 December 2020

We’ve had another week of lacklustre sunspot activity. The solar flux index has been pegged at around 82, caused by the two tiny sunspots in active region 2793. Having said that, a lack of coronal hole activity has meant that geomagnetic conditions have been settled, with a maximum Kp index of two, but more often than not it was actually …
