Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-08-18T11:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2023-08-18T11:36:00-CME-001 (version 1)
Source Location: N21W40
Active Region Number: 13409
Note Keyword:
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
Morphology Keyword:
Note: CME visible in the NW in SOHO LASCO C2/C3 and faintly in STEREO A COR2, associated with a C1.7 flare from AR 3409 (N21W40) peaking at 2023-08-18T10:48Z. The eruption is best seen in SDO AIA 171/193 as brightening at the site of the eruption starting at 2023-08-18T10:34Z, opening field lines, and small post-eruptive arcades. Another speculated source which may have produced a smaller overlapping feature in the coronagraphs is the liftoff of some prominence material seen at about N50W90 in GOES SUVI 304 and opening/disappearing field lines seen in SDO AIA 171 at about 2023-08-18T10:30Z.

CME measured using source location of AR 13409 (N21W40). Leading edge is extremely faint in STEREO A COR2 difference imagery and becomes diffuse after three frames. SOHO LASCO C2 and C3 difference imagery in swpc_cat appear to be in some kind of campaign mode lasting from 2023-08-18T12:27Z to 2023-08-18T14:47Z in C2, and from 2023-08-18T12:18Z to 2023-08-18T14:51Z in running difference imagery. |
