Did manage several contacts on 6 meter SSB. Even tried 6 meter AM but the AM stuff was only running low power and the antenna was only a temporary 3 element beam. The 7 element long boom yagi won't be back up till later in the Spring. All the rest of the contacts and on the other VHF/UHF bands were done on CW.

At 1000Z yesterday morning on the Saturday morning Old Military Radio Net all stations way to the south and west were if anything stronger than usual. However, NCS KD3HT Steve in the Poconos of PA and all New England stations to my north were uncopyable. An aftershock of the big mag storm was going on with a K index of
4 to 5. At 1050 within a minute or so, KW1Is signal jumped from barely audible to 20 over 9. Checked our local sunrise and it happened about 2 minutes before Dale's signal jumped up. We have observed this "sunrise effect" for many years when the band is otherwise very long during the first part of the net. I assume the cause has something to do with sunlight affecting the D layer.
There is an interesting posting on Spaceweather.com re the effect of the recent solar eclipse at high latitudes on VLF station signal levels received in notherern Europe. A signal from Iceland was enhanced, and levels from the Navy station down in Puerto Rico dropped way down during the eclipse.

The grey line segment of time at sunrise and sunset can usually provide a segment of enhanced propagation.
