Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-08-12T08:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-08-12T08:00:00-CME-001 (version 2)
Note Keyword:
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: This CME is visible to the SW in SOHO LASCO C2/C3 and STEREO A COR2 Difference coronagraph imagery. The source is likely a small eruption and moving field lines seen on and just beyond the W limb in GOES SUVI 284 at about 2023-08-12T05:45Z. One possible candidate active region for the eruption is former AR13398 which is estimated to be located at S20W120. This CME is measured with an approximated longitude due to a lack of stereoscopic viewpoints. Longitude is +/- 20 degrees.
