Issued on 2023 Mar 21 1553 UTC
A filament erupted in the north-east quadrant near NOAA AR 3258 around 13:00 UTC on March 20th and long duration C4.4-class flaring was produced by this region with start time 15 UTC, peak time 13:34 UTC, end time 18:14 UTC. A resulting coronal mass ejection (CME) was first observed in the LASCO/C2 imagery around 15 UTC. While the bulk of the CME is off the Sun-Earth line, a glancing blow could reach Earth on March 23rd. Earlier, a wide CME lifted off the south-west quadrant around 14:14 UTC on March 20th, accompanied by large scale magnetic field reconfiguration. This CME is considered to be back-sided with no expected impact at Earth.
