Propagation News – 9 May 2021
The Sun was devoid of sunspots last week, which saw the solar flux index plummet to 70 – pretty much what it is around sunspot minimum. The good news is that an active region is rotating into view. Region 2817 is currently just on the Sun’s eastern limb as this report is being prepared and […]
Propagation News – 2 May 2021
Last week was characterised by relatively low sunspot numbers, but reasonably settled geomagnetic conditions. The solar flux index never rose above 80 all week, despite a large cluster of sunspots. This cluster, composed of regions 2818, 2820 and 2821, were responsible for some C-class solar flare activity, but never really grew into anything. By the […]

Last week was marked by solar flares, perhaps giving us a taste of things to come as the solar cycle progresses. The Kp index hit four on Monday after the weekend’s high of five. But luckily things then calmed down and we have been seeing the Kp index down to two overall. There was even […]

The Sun continued to remain quiet last week with a maximum solar flux index of 75.3 on the twelfth and a maximum sunspot number of 17. Sunspot region 2814, whose physical width was equivalent to four Earth diameters, spawned a few B-class solar flares, but showed little sign of growing and as you read or […]

We had yet another week with poor sunspot numbers. Although we started the week with a sunspot number of 11, representing one spot in one group, it didn’t take long for this to decline and we were back to zero spots again and a solar flux index of 76. What we did have, however, were […]
Propagation News – 4 April 2021
This last week has certainly been quieter from a geomagnetic disturbance point of view. We have seen the Kp index at one for much of the time, and it even hit zero in the early hours of Tuesday the 30th. We have not been quite so lucky on the sunspot front, with zero spots being […]
