Solar activity was at lower levels this week. The Solar Flux Index declined to 91 on the 29th, before recovering toward the end of the week. However, it never quite reached 100. Geomagnetic conditions were reasonably settled, with the A index in single figures and the K index hovering between one and three. This was […]

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 NOAA had predicted around 100 to 110. The K-index also fluctuated […]

This week has been a mixed bag in terms of HF performance. At times 10 metres has been open, with the 7P8C DXpedition to Lesotho putting in an appearance on the band for hours on Monday and Tuesday. But the high-speed solar wind is never far away and played havoc with geomagnetic conditions later on […]

This past week saw an increase in the solar flux index, helped along by a gaggle of sunspots. The SFI hovered around 117 mid-week which, when coupled with relatively settled geomagnetic conditions, brought some life to the upper HF bands. Andy, M0NKR reported working Japan on 20 metres from his car at lunchtime using a […]

Last week’s HF propagation was spoiled by a K5 geomagnetic event in the early hours of Wednesday morning. This was caused by an enhanced high-speed solar wind stream. This had the effect of knocking the HF bands for six with the VP8SGI DXpedition on South Georgia barely making an appearance for modestly-equipped stations for the […]

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 […]
