Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-15T01:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-02-15T01:36:00-CME-001 (version 3)
Note Keyword:
COL: Possible collision with previous CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
U: Unknown
Note: Diffuse CME seen to the SW in SOHO LASCO C2/C3 and STEREO A COR2. Source is a set of successive opening field lines on the SW limb, with the identified leading edge at 2024-02-15T01:36Z likely attributable to the instance of opening field lines seen occurring at 2024-02-15T00:52Z in SDO AIA 171. A subsequent instance of opening field lines are seen from the same location starting at 2024-02-15T02:33Z as seen in SDO AIA 193, which likely resulted in an additional faint front first seen in SOHO LASCO C2 at 2024-02-15T03:24Z. There is an earlier instance of opening field lines at 2024-02-14T22:42Z in SDO AIA 193 with related dimming seen centered at W70N10 at 2024-02-15T00:36Z, but this does not seem to have resulted in any visible 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 |
