Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-05-27T20:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2023-05-27T20:00:00-CME-001 (version 1)
Source Location: S25W35
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
U: Unknown
Note: Source is rising/opening field lines seen in the SW on the Earth-facing disk at about 2023-05-27T19:30Z in GOES SUVI 284. These field lines are seen rapidly opening after a C6.2 flare from AR 13312, which was at S25W35 at the time. Brightening is seen in SDO AIA 171/304 due to the flare. Footpoints of the opening field lines appear to reach from AR13312 (S25W35) to AR13310 (S20W57) at 19:30Z.

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.

CME Analysis M2M_CATALOG LE true StereoCAT 30.0 -52.0 348.0 S 34.0 2023-05-28T05:58Z Measurement using best fit between coronagraphs. There is heavy southern deflection, which was anticipated given the signatures in UV imagery. This CME is very faint in difference imagery and was too faint to distinguish in C3 difference imagery. 1: Result 1 (2.0 AU)
