The last week was characterised by unsettled geomagnetic conditions, but a reasonable solar flux index of 92, falling to 86. Despite NOAA predicting that the Kp index would be around two, we had an excursion up to five on Tuesday. This was due to an enhanced solar wind stream containing a sector of southward Bz, […]

We had yet another week with low solar activity. The solar flux index started the week at 79 and by Thursday had only climbed to 83. Ideally, we want the SFI to be above 100 to guarantee good 10m openings. Geomagnetically, the Sun has been quiet with a maximum Kp index of three. On Thursday […]

We had a week of lower sunspot activity, almost back to the days of sunspot minimum. The solar flux index ranged from 78 on Sunday 14th to 79 on Thursday 18th with a high of 80 on the 16th. So, nothing to write home about there. Geomagnetic conditions were mainly unsettled, with a maximum Kp […]

That isn’t to say that the Sun has been inactive – far from it. A long-duration M2.0 solar flare took place […]
