Propagation News – 7 November 2021
What a roller coaster week we had. From great conditions on HF last weekend, to a severe geomagnetic storm this week, it has been hard to predict what’s coming next. The Kp index hit seven on Thursday, thanks to incoming plasma from a full halo coronal mass ejection produced by an M1.7 flare from active […]

Well, we had another topsy-turvy week, with the sunspot number going from a lowly 10 to a much more impressive 91. We started last week with a virtually spotless solar surface, but this week the Sun is peppered with spots, with five active regions in place on Thursday. The net result is the maximum usable […]

After a week of sunspots and DX fun it looks like we are back in the doldrums again. The Sun currently has just one sunspot visible, meaning the sunspot number is 11. This represents one sunspot in one group. There has been DX to be had, mostly thanks to DXpeditions, including Guinea Bissau, J5T, The […]

Last week saw a mixed bag in terms of HF propagation with good conditions at times, but horrendous conditions mid week after a coronal mass ejection saw the Kp index shoot up to six. Matter from the CME, which was accompanied by an M1.6 solar flare on the 9th of October, hit the Earth in […]

Solar activity has dipped a little over the last two weeks. From a solar flux high of 102 on the 20th of September, activity declined to the mid-80s and stayed there. That isn’t to say that HF activity has been poor. Far from it. There are numerous reports of DX being worked, including S9OK on […]
Propagation News – 3 October 2021
Life is starting to get a bit more interesting in terms of the Sun and HF propagation. This week we have seen more sunspots, a coronal mass ejection and some minor solar flares, so the Sun is definitely waking up. The solar flux index passed 100 on Thursday, reaching 102. This is high enough to […]
