Coronal Mass Ejection

Start Time: 2025-03-21T16:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-03-21T16:00:00-CME-001 (version 1)
Source Location: N02E07
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
Note: Faint halo CME with a bulk visible mainly to the SE in SOHO LASCO C2 and C3 imagery (more easily seen in difference imagery). There is no STEREO A COR2 imagery for this event due to a data gap. The source of this CME appears to be a large dimming region centered near N02E07 starting around 2025-03-21T15:49Z with a southeast directionality based on the minor EUV wave visible in SDO/AIA 211 and 193 imagery. There's a large coronal hole situated E/SE of the dimming region and a separate coronal hole due west of the dimming region which may have contributed to the deflection visible on the solar disk in SDO/AIA imagery. This source location appears to be a sympathetic eruption to the M1.2 flare from AR14028 (S17W33) seen to the SW in SDO/AIA 131 imagery.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type |

Parameters based on the BULK of the CME using SOHO LASCO C2 imagery. The front of the bulk is not clearly visible in SOHO LASCO C3 imagery due to the control arm. High uncertainty of parameters due to limited stereoscopic viewpoints. |
