Propagation News – 27 December 2015
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 […]
Propagation News – 13 December 2015
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 […]
Propagation News – 29 November 2015
This week has been geomagnetically quiet with the K-index hovering around zero or one. This is in contrast to the extremely unsettled conditions we have been having on and off over the past few months. Coupled with a solar flux index of around 110 to 120 this has brought reasonably settled conditions on HF and […]
Propagation News – 22 November 2015
This week has been a bit of a mixed bag in terms of HF propagation. The early part of the week saw reasonable openings on 18 and 21MHz, although a continuous K-index of around three due to the high speed solar wind stream, took its toll. The VK9WA Willis Island DXpedition was even audible on […]
