A long-duration C2 solar flare erupted from an area west of AR 2962 on March 10/11, 2022, producing full halo coronal mass ejection (CME). As a result, a G2 - Moderate geomagnetic storm watch is in effect.

The event started around 18:00 UTC on March 10 and ended after 05:00 UTC on March 11 - more than 11 hours.

The CME was first observed in LASCO C2 imagery at around 19:30 UTC on March 10.

The arrival of this CME is expected on the 33rd anniversary of the infamously named "Quebec Blackout" geomagnetic storm in March 1989, which resulted in power outages in Canada as well as auroral activity in lower than usual latitudes.
