Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-08-12T03:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-08-12T03:48:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: This CME is part of a continuous outflow seen to the SW in coronagraph imagery. The source for this can be seen in GOES SUVI 284 as faint moving opening field lines beyond the SW limb at about 2023-08-12T02:52Z. This CME was seen in STEREO A COR2 running difference imagery due to current low quality of STEREO A COR2 white light imagery. This CME is measured with an approximated longitude based on the estimated location of AR13398 (S20W107) due to a lack of stereoscopic viewpoints. Longitude is +/- 20 degrees.
