Solar alert

Issued on 2023 Sep 04 0905 UTC

A partial halo Coronal Mass Ejection (CME), with angular width of 170 degrees first appeared in the SOHO/LASCO-C2 field of view at 05:24 UTC on September 03. The CME was associated with the C5.9 flare which peaked at 06:15 UTC on September 03, from NOAA AR 3413. Another partial halo CME, with angular width around 198 degrees erupted towards the north-west at 09:12 UTC on September 03 (as seen by LASCO-C2). It was related to an M6.0, peaking at 08:36 UTC on September 03, from NOAA AR 3413. The source region of the CMEs is slightly behind the west limb, and it is therefore not expected to affect the Earth.
