Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-05-09T04:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-05-09T04:24:00-CME-001 (version 1)
Source Location: N14W26
Active Region Number: 13296
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
Morphology Keyword:
U: Unknown
Note: This CME is faintly seen to the NW in SOHO LASCO C2, C3, and STEREO A COR2 after it returns from a data gap. There are multiple CMEs and outflows overlapping this CME while it moves through the C3 and COR2A fields of view. The source of this CME is likely the M6.5 flare from AR13296 peaking at 2023-05-09T03:54Z.

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

Also, this measurement is based on the best fit between SOHO LASCO C2/C3 and STEREO A COR2 so the longitude may vary +/- 10 degrees. Not modeled Carina Alden on 2023-05-09T19:08Z
