Solar alert

Issued on 2024 Feb 29 0953 UTC

A westward partial halo coronal mass ejection (CME) was detected in the LASCO/C2 data at 17:48 UTC on February 28. The CME originated from NOAA AR 3590 in the north-west quadrant of the solar visible disk, and was associated with a long-duration M1.3-class flare peaking at 18:19 UTC. No increase in the greater than 10 MeV proton flux has been detected in association to this eruption. The CME has an estimated speed of around 500 km/s and may result in a flank encounter at Earth on March 3. Unsettled to active geomagnetic conditions are expected due to the arrival of the interplanetary CME.
