This week was a mixed bag in terms of the sun and HF propagation. The solar flux index hovered around the 80 mark, but there was a geomagnetic disturbance on Tuesday evening that sent the K-index up to five for more than six hours. This prompted warnings that aurora might be visible from lower than […]

This week has been a little unsettled in terms of geomagnetic disturbances and we are still experiencing the summer HF doldrums, at least until September. The K index hit three on many occasions due to ongoing coronal hole activity, and these negated the slight rise in the solar flux index caused by a handful of […]

Last week the solar flux index climbed as NOAA had predicted, hitting 95 by Thursday evening. This was largely due to a new large crop of sunspots on the sun’s surface. These will rotate across the sun over the next few days and, as long as they don’t fade away, they should help the solar […]

This week saw the effects of yet another solar coronal hole, which pushed the Kp-index to four and five on Wednesday and Thursday. We predicted this last week, but were out by one day. Lacklustre sunspot activity also meant that the IOTA contest saw many contestants staying on 20m and below, with the odd foray […]

This week we have been looking once again at a blank solar disk. The spotless sun offered a solar flux index of 72 on Thursday, just six points up from a typical solar minimum figure. Unfortunately, the bad news doesn’t stop there. There were poor geomagnetic conditions last weekend thanks to the effects of a […]

There was plenty of solar action this week. The solar flux index climbed to 108 on Thursday thanks to a slew of sunspots. Plus we had incoming plasma from a coronal mass ejection that sent the K-index up to five for nine hours in the early hours of Wednesday 20th. There have also been some […]
