A magnificent halo CME billowed away from the farside of the sun yesterday,
the second time this week this has happened. A hidden sunspot group transiting the farside is crackling with activity. If it were facing Earth, we would now be bracing for geomagnetic storms.

New Update:
New data courtesy of the ESA Solar Orbiter shows that the large CME observed yesterday was the result of a solar flare reaching at least the X2 level. In addition to this, the energetic CME observed on Tuesday was the result of an X3 event. It appears that we have a very active sunspot region
on the farside of the Sun, and we will see this region turn into view within a week or so.
