Space Weather

The CME has reached L1 with a strong southward Bz component. Aurora watchers get ready for a good show in around 45-60 minutes! It looks like a strong shock is incoming.

Space Weather

A strong substorm is in progress at high latitudes. Aurora possible.

Magnetometers on the Goes satellites have dropped sharply, suggesting incoming turbulence in the solar wind. Further geomagnetic storming is likely tonight.

Space Weather

Activity is still officially "boring", but are things about to change?

The farside monitor shows that the mysterious blob (an area of magnetic activity) will soon be appearing over the east limb. Huge magnetic loops above the limb are suggesting something interesting is coming!

@efi Have to wait and see. If this is a dying region it might not even fire off any flares.
