Propagation News – 29 January 2017
Last week saw a flurry of sunspots appear that pushed the solar flux index to 87 on the 22nd. Geomagnetic conditions were unsettled last weekend, but this week has largely seen a respite, with the K-index often being one or even zero. This resulted in good conditions with the maximum useable frequency hitting at least […]
Propagation News – 22 January 2017
We saw a couple of sunspots last week, but they weren’t enough to make a major difference to HF propagation. This was due in part to a raised K-index, thanks to solar material from a recurrent coronal hole. NOAA released a geomagnetic storm warning for the 18th and 19th. The solar index remained in the […]
Propagation News – 15 January 2017
The predicted poor geomagnetic conditions last week were not quite so bad, due to the incoming high speed stream from a coronal hole having a mostly north-facing Bz field. This was less likely to couple with the earth’s magnetic field and we didn’t see the very high K indices and poor auroral conditions we expected. […]
Propagation News – 8 January 2017
Firstly, a happy New Year to all. We’ve got off to a bad start with a massive coronal hole on the sun that has rewarded us with dire predictions for the period up to 8 January. We can expect the K-index to hit four or five at times with a consequent lowering of maximum useable […]
Propagation News – 25 December 2016
This week we have an extended propagation bulletin that takes you through to January 8th. HF propagation will continue to be relatively lacklustre, with the solar flux index staying in the mid to high 70s. Geomagnetic conditions have been unsettled at times, thanks to recurrent coronal hole activity. We will have a fairly quiet week […]
Propagation News – 18 December 2016
This week we have a slightly different approach to the HF propagation news. We want to help you and your family contact Santa’s elves in Lapland, Finland. The station OF9X is once again on the air this Christmas from Santa Claus Land in the Arctic Circle. Twelve elves are operating OF9X, which stands for ‘Old-Father-Nine-Christmas’, […]
