Propagation News – 28 February 2016
This week didn’t bring the better HF conditions that we talked about in the last GB2RS. This was due to a declining solar flux index and generally active geomagnetic conditions. The SFI declined to 88 by Thursday due to a lack of sunspots, although NOAAhad predicted around 100 to 110. The K-index also fluctuated between one and three due to ongoing solar coronal holes, although there were no major geomagnetic events. Together this brought reasonable propagation during the ARRL DX CW contest, with many of the eastern and mid-western states being workable up to 21MHz, but 10 metre openings were a little lacklustre.
