Tonight is the night for 2M propogation? Troposhperic ducting?
If you want to see how far your signal can go, you might want to get on simplex 2M tonight and listen...

If their predictions are true, it could be AWESOME!

COMPLEX ERUPTION ON THE SUN: This morning around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was sunspot 1092. At about the same time, an enormous magnetic filament stretching across the sun's northern hemisphere erupted. NASA's Solar Dynamics Observatory recorded the action:

The timing of these events suggest they are connected, and a review of SDO movies strengthens that conclusion. Despite the ~400,000 km distance between them, the sunspot and filament seem to erupt together; they are probably connected by long-range magnetic fields. In this movie (171 ), a shadowy shock wave (a "solar tsunami") can be seen emerging from the flare site and rippling across the northern hemisphere into the filament's eruption zone. That may have helped propel the filament into space.

In short, we have just witnessed a complex global eruption involving almost the entire Earth-facing side of the sun.

A coronal mass ejection (CME) produced by the event is heading directly for Earth: SOHO movie. High-latitude sky watchers should be alert for auroras when it arrives on or about August 3rd.

Maybe, if the geomag storm from the CME doesn't fry your radio. :-)

Terrestrial weather=Tropo

Hummmmmm.....Polar path to Europe, on 6, maybe?
