Propagation News – 15 May 2016
The solar flux index hovered teasingly just below 90 this week, trying to make us believe that we are not heading towards the next sunspot minimum. There were no significant solar flares, but we did have geomagnetic disturbances, particularly at the beginning of the week. This was due to an ongoing high-speed solar wind stream […]

The solar flux index held steadfast at 90 for most of the week, but geomagnetic conditions remained unsettled with the K-index hitting five on Bank Holiday Monday. The latter half of the week was a little more settled, bringing better HF conditions with only a few minor C-class solar flares. At the time of writing, […]

It’s been another mixed week, with coronal holes dominating once again. The K-index, a measure of the disturbance to the Earth’s magnetic field due to incoming solar plasma, fluctuated all week, being as low as one and as high as four. The solar flux index started the week at 82, but rose steadily to reach […]

It has been week of mixed HF propagation, good at times and lousy at others. The solar flux index declined from 102 on Sunday to 83 on Thursday, as only one lonely little sunspot remained visible. The K-index, which is the three-hourly measure of geomagnetic disturbance due to incoming plasma from the Sun, has also […]

No sooner did we say that it was beginning to look like the start of a solar minimum than an enormous sunspot appeared around the sun’s limb. Sunspot 2529 has produced a number of B and C-class solar flares. And despite NOAA predicting a solar flux index of around 80 last week, it rocketed to […]
Propagation News – 10 April 2016
It is beginning to look like we’re getting an early taste of the upcoming solar minimum. The sun currently only has one small sunspot group and, at the time of writing, there were no new spots coming up behind it. The solar flux index hovered in the low to mid-eighties this week, giving a noon-time […]
