Propagation News – 31 January 2016
Solar activity was a little more settled last week. The solar flux index was in the range 104-113 and the K index was mainly around one or two later in the week, after reaching four on Sunday. This week the solar flux index is predicted to remain in the range 100-118, with lower activity on […]
Propagation News – 24 January 2016
We’ve had yet another week with unsettled geomagnetic conditions. This time the Kp index hit five on Wednesday, and even six on Thursday, caused by a plasma emission from the Sun with a prolonged southward-facing Bz field. This was a shame as the field had been very settled on Monday, with a Kp index of […]
Propagation News – 17 January 2016
We’ve had another week of disturbed geomagnetic conditions, with the K index hitting four at times. This was due to an ongoing high-speed solar wind stream from a coronal hole on the sun. As we predicted, the solar flux index remained in the range 100-110, bringing lacklustre HF performance at times. Next week looks like […]

As we’ve entered 2016 it would be nice to have some better HF propagation conditions. Unfortunately, life is never that simple or accommodating! This week we have suffered from the effects of a high speed solar wind stream that flowed from a geo-effective coronal hole on the sun. The effect was a K-index of five […]

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 Oscar Foxtrot Nine X-ray, OF9X, is once again on the air this Christmas from Santa Claus land in the Arctic Circle. The station, which is near […]
Propagation News – 20 December 2015
The smoothed sunspot number for December is 46.1. This time last year it was 63.7, which shows how we are sliding down solar cycle 24. Coronal mass ejections and coronal holes continue to cause problems at times, with the K-index hitting five on Tuesday the 15th. As the incoming plasma hits the earth you can […]
