Solar alert

Issued on 2021 Aug 24 2021 UTC

In the first hours of August 23rd, the eruption of a large filament situated close to the extension of the northern polar coronal hole (down to 25 degrees), was observed. The filament eruption was associated with the faint and slow partial halo CME (angular width of about 180 degrees and velocity about 450 km/s). The CME was first observed in the SOHO LASCO C2 field of view at about 06:00 UT. We expect arrival of the CME at Earth in the afternoon of August 26.
