Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-05T15:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-05-05T15:48:00-CME-001 (version 2)
Source Location: S19E20
Active Region Number: 13663
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
BR: Brightening
DIM: Dimming
Morphology Keyword:
LS: Loop and Shock Candidate
Note: A faint CME to the SE with multiple successive fronts/outflows. It may be associated with the flaring activity in AR 3664 (S19E18) and AR 3668 that was sympathetic to higher intensity (M-class) flaring in AR 3663. In terms of coronal signatures, there is a flare in/south of AR 3664 starting around 2024-05-05T14:30Z and a dimming in AIA 193 south of the AR, as well as some post-eruptive arcades following it. A separate smaller dimming appears at S30E05 and could be responsible for the more western brighter front/edge of the front in coronagraph. The CME is fully covered by a data gap in STEREO.

A very speculative final analysis using LASCO imagery only. The CME front is faint and the source - minor flaring and eruptive activity in Active Regions 3664 and 3668 - is tentative. |

POS analysis is the most definitive analysis of this event since the source is rather unclear. |

Very preliminary and speculative analysis of this faint asymmetrical CME with SOHO LASCO imagery only and based on the assumption that minor eruptive/flaring activity in Active Region 3664 and 3668 was the source of this event. |
