Hi Topbanders

I have an opposite experience to influence of solar wind to propagation to Pacific.
I do follow daily solar wind speed and dynamic pressure.
Here is the page:

As soon as solar wind speed is close to 200 km/s and dynamic pressure about 0,1 nPa there is for sure good propagation to NA, Pacific and JA-directions.

I did work ZL3IX, Greg also on 20th DEC. He had a very good signal that evening. There are always exceptions to those rules.

Season's Greetings

Ilmo, OH2BO
