Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-01-31T21:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C3
Activity ID: 2023-01-31T21:09:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME

Morphology Keyword:
Note: This CME is faintly seen to the S/SE in SOHO LASCO C3 and STEREO A COR2 imagery. There appears to be a second front following shortly after (starting around 2023-01-31T22:23Z) that is not clearly separable in difference imagery. Therefore, this entry encompasses both features. There is no clear source for this CME as it appears to be farsided.

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
