Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-06-13T12:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-06-13T12:00:00-CME-001 (version 1)
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:
U: Unknown
Note: This faint and moderately narrow CME first can be seen to the west in SOHO LASCO C2/C3 and STEREO A COR2 in white light imagery. There were three candidate source locations for this CME, but the one I feel most confident about is an opening of field lines seen on/just beyond the western limb at about S10, best seen in GOES SUVI 284 starting at 2023-06-13T11:25Z. The two other candidate sources were: 1) a small eruption at S10W35 at 2023-06-13T09:40Z, seen as dimming in GOES SUVI 284, and 2) a rising and opening loop of field lines seen in GOES 195, on/just over the SW limb, which also occurs at 2023-06-13T09:40Z. These two alternate sources DO NOT appear to be linked, however, as their directions are slightly different, and the rising loop appears to be originating from the limb (it's not just opening field lines that could be tracible back to S10W35, for example.)

This CME was tricky to measure as the leading edge is faint and becomes too diffuse to measure at about halfway through STEREO A COR2 field of view (in difference imagery). The CME was too faint to confidently measure in C3. |
