Propagation News – 5 June 2016
The solar flux index declined further this week to the mid-80s. A quick look at an image of the Sun from the Solar Dynamics Observatory on solarham.net shows why. On Thursday two sunspot groups were rotating out of sight on the Sun’s limb, leaving a pretty blank disk. As a result NOAA predicts the solar […]

This past week was more settled geomagnetically with the K-index generally staying around zero or one. This was thanks to a lack of solar coronal hole activity and the associated high-speed solar wind streams. The solar flux index declined from the high to mid 90s as large sunspot 2546 rotated out of view. This has […]
Propagation News – 22 May 2016
This week the solar flux index managed to remain mostly above 100, thanks in part to large sunspot number 2546. The region appears to be quite stable and not a likely threat for any significant solar flares. Geomagnetic conditions remained unsettled with the K-index hitting four at times and often hovering between two and three. […]

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, […]
Propagation News – 1 May 2016
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 […]
