As predicted, a solar wind stream engulfed Earth on Nov. 7th, but the geomagnetic storms it is producing are stronger than expected
The NOAA Space Weather Prediction Center (SWPC) said a G1 (minor) geomagnetic storm watch has been issued for October 24, and a G2 (moderate) geomagnetic storm watch has been issued for October 25.
In a G1 storm, weak power-grid fluctuations can occur, minor impact on satellite operations is possible, migratory animals may be affected, and aurora borealis is commonly visible at higher latitudes …

The October 4 webinar, “A Look at Propagation for the 2017 2018 Contest Season,” sponsored by the World Wide Radio Operators Foundation (WWROF), has been posted. Conducting the webinar were Carl Luetzelschwab, K9LA, and Frank Donovan, W3LPL. Contesters and DXers alike will appreciate their predictions and suggestions as to what to expect over the next few years in terms of HF conditions.
The current disturbance level is at 309.7nT. Pity we have clouds in Birmingham (UK) but they have quite a nice pink tinge to them.
Both professional and citizen scientists conducted formal and informal investigations into the effect of the August 21 solar eclipse on HF radio propagation. Nathaniel Frissell, W2NAF, of HamSCI, has said it will take some time to get a more scientific analysis of data compiled during the Solar Eclipse QSO Party. Frissell and others are investigating whether the sudden absence of sunlight durin…
