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 […]

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 […]

This past week saw continued low to medium geomagnetic disturbances thanks to ongoing solar coronal holes. A geomagnetic storm watch has been issued for the 2nd of April due to a disturbed interplanetary magnetic field, coupled with elevated solar wind speeds from a coronal hole high speed stream. This could see the K index climb […]

This week has seen more settled geomagnetic conditions with the K-index hovering around two, although Wednesday saw it spike up to four due to a high speed solar wind stream from a coronal hole. Sunspot wise, the solar surface was a little lacklustre, with just one sunspot group visible. This pushed the solar flux index […]

This week has seen continued geomagnetic storms, thanks to a high-speed solar wind stream flowing from a geo-effective coronal hole on the sun’s surface. As we predicted, last weekend was reasonably settled, but then it all went pear shaped. The K-index hit five on Tuesday night, and five again on Wednesday night, this time remaining […]
