Solar alert

Issued on 2022 Mar 11 0733 UTC

A full halo coronal mass ejection (CME) was detected in SoHO LASCO C2 and C3 coronagraph data with start time around 18:48UT on March 10th following the onset on a long duration C2.8-class flare from active region NOAA 2962. The bulk of the CME covers almost 180 degrees (north-east to north-west from Earth's perspective) and splits into two parts, moving at different projected velocities, both exceeding 500 km/s. The CME is observed by STEREO A COR2 primarily to the north-west and has a substantial Earth-directed component. Further analysis will be conducted to estimate the expected arrival time.
