Prediction for CME (2023-06-04T10:24:00-CME-001)CME Observed Time: 2023-06-04T10:24ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/25453/-1 CME Note: CME seen to the southwest in all coronagraphs (SOHO LASCO C2/C3, STEREO A COR2). Leading edge is faint and wide. Source is a large filament eruption seen spanning from about S32W10 to S10W50 in SDO AIA 304 starting at about 2023-06-04T09:00Z (Centered at S25W30). Post-eruptive dimming can be seen in SDO AIA 193 along the southwest quadrant of the Sun at 09:27Z, and ejecta can be seen off the southwest limb in SDO AIA 171 at 09:42Z. The filament can also be seen erupting in STEREO A EUVI 195/304 starting at 08:25Z/8:15Z, respectively. From LASSOS team discussion: this signature is likely a flank arrival of a CME passing West of Earth.

A 35 degree long filament, centered near S20W33, lifted off between 04/0830-1000 UTC. A portion of the material was observed moving north, but a portion did escape off the SW limb as observed in SOHO LASCO imagery. The resultant CME was first observed in LASCO C2 imagery at 04/1036 UTC. Analysis and modeling of the event suggested possible influence from the periphery of the CME on 08 Jun.Lead Time: 73.08 hour(s) Difference: -5.08 hour(s) Prediction submitted by Anna Chulaki (M2M Office) on 2023-06-04T21:20Z |
