Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-08-17T17:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-08-17T17:36:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
Morphology Keyword:
O: Other
Note: This CME is visible to the NW in SOHO LASCO C2/C3 and STEREO A COR2 Difference coronagraph imagery. The source is unclear but may be a small eruption and associated C2.2 flare from AR 13397 (N16W80) seen only as opening field lines, and as post-eruptive loops seen starting at 17:40Z in SDO AIA 193.

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

CME Analysis M2M_CATALOG LE true SWPC_CAT 80.0 13.0 762.0 C 27.0 2023-08-17T21:37Z Measured with an approximated longitude of the source location (AR 13397 at W80) due to a lack of stereoscopic viewpoints. STEREO A COR2 was in a data gap for the duration of when this CME would be in the Field of View. 1: Result 1 (2.0 AU)
