Activity ID: 2021-05-22T09:12:00-CME-001 (version 7)
Active Region Number: 12824
Note Keyword:
Source Signature Keyword:
FLR: Flare
Morphology Keyword:
Note: Source is an eruption from AR 2824 starting after 06:15Z, with subsequent dimming towards the south of the AR. Material is seen in AIA 193 and 304 around moving outward after 06:45Z to the West in relation to the AR position and also to the South. In STEREO A Cor2 there are actually two CMEs seen, one in NW starting at 08:23 and another in SW starting at 09:38. The later CME might be associated with one of the later C-class flares from AR 2834 (e.g, flare starting at 6:45). The CMEs appear merging and are seen as one in SOHO/LASCO C2 and C3. They were analyzed as one CME.

If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME |

In STEREO A Cor2 there are actually two CMEs seen, one in NW starting at 08:23 and another in SW starting at 09:38. The CMEs were analyzed as one CME (as fitting as two CMEs yielded almost the same parameters and was difficult). |
