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 […]
Propagation News – 10 January 2016
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 […]

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 […]

This has been another week with an elevated solar wind stream from coronal holes. This had a negative effect on the geomagnetic field, which reached storm levels at times again with visible aurora at higher latitudes. The solar wind often had a south-facing magnetic Bz component, which meant it coupled more easily with the earth’s […]
Propagation News – 6 December 2015
Last weekend saw reasonably settled conditions for the CQ Worldwide contest, with DX to be had on all the upper HF bands. However, 10 metres was a little lacklustre this year due to the lower solar flux index compared with 2014. Twenty and 15 metres proved to be the ‘money bands’ as the flux dipped […]
