Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-31T14:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-05-31T14:23:00-CME-001 (version 1)
Source Location: N15E08
Active Region Number: 14100
Note Keyword:
Faint: Faint event; may affect type assignment
HAL: Halo CME
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
Note: Partial halo CME first seen in the East by STEREO A COR2 beginning at 2025-05-31T14:23Z. This CME is seen VERY faintly in SOHO LASCO C3 and GOES CCOR as a full halo signature in later frames. There is no abundantly clear source for this event. There is a small region of brightening and field line movement from AR 14100 (N15E08) beginning at approx. 2025-05-31T13:34Z as seen in SDO AIA 94 and 211 that may be associated with this CME.

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 |
