Propagation News – 20 November 2016
Last week, the solar flux index hovered around the 80 mark, with average sunspot counts reaching their lowest level in five years. With sunspot minimum predicted to be some time in 2018 or 2019, this is a taste of what we can expect for the time being. But it wasn’t all bad news, as geomagnetic […]
Propagation News – 13 November 2016
Last week saw DX being worked on HF as more-settled geomagnetic conditions allowed the ionosphere to strengthen. There were reports of US stations being worked on 40m before midnight, and DX contacts on 20m, 17m and 15m across the globe. The solar flux index remained in the high 70s, and the geomagnetic K index remained […]
Propagation News – 6 November 2016
Last week, the solar flux index remained in the mid to high 70s, but HF propagation was once again dominated by variable geomagnetic conditions. The first half of the week, which included the CQ Worldwide contest, was very unsettled with the K index at high latitudes peaking at seven. This drove down maximum useable frequencies […]
Propagation News – 30 October 2016
Last week was characterised by low sunspot activity, but very unsettled geomagnetic conditions. The solar flux index was in the mid to high 70s, but the K index was five or six for days on end, and even peaked at seven. This was high enough for automatic visible aurora e-mail warnings to be sent out […]
Propagation News – 23 October 2016
Last week the solar flux index fell back to the high 70s. Geomagnetic conditions were unsettled over the weekend, but improved as the week went on. We are well and truly into the autumn HF season now, which is reflected in higher daytime maximum usable frequencies and lower night-time ones. However, we continue to be […]
Propagation News – 16 October 2016
The solar flux hovered around the 100 mark and, as predicted, HF propagation showed a big improvement earlier in the week thanks to more settled geomagnetic conditions. There were many reports of DX being worked from the UK including H40GC in Temotu, Solomon Islands, and T31T in Central Kiribati. The Kp-index was in the range […]
