This is the 2nd Coronal Cavity in 2 weeks….now from what I can gather, this is not the norm.
Helioviewer shows activity of a filament on the south west rim of the sun, there is an hour plus long gap in the video on the 19th.. The magnetoshpere simulation has been down for almost if not a week (a first since I have started watching it):
…and now there is talk about the whole magnetoshpere switching directions.
So what really is going on?
