Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-07-31T23:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-07-31T23:36:00-CME-001 (version 1)
Source Location: N10E05
Active Region Number: 13386
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
U: Unknown
Note: This CME is first seen to the NE in SOHO LASCO C2 at 2023-07-31T23:36Z in both white light and difference imagery. The source of this CME is likely the northern portion (from N15 to S10) of a filament which erupted at central meridian and seems to have deflected to the NE as seen in UV imagery. The northern portion of the filament seems to lift off at about 2023-07-31T17:30Z, as seen in SDO AIA 304 (though, it is difficult to discern exact time due to having only a face-on view of the solar disk). This CME overlaps with a prior CME which likely has a source on the far side of the solar disk.

CME Analysis M2M_CATALOG LE true SWPC_CAT -23.0 10.0 636.0 C 19.0 2023-08-01T04:05Z This CME is measured using an estimate of the source location based on UV imagery. The eruption of the northern portion of filament stretches from N15-S10 and at E05 on the solar disk. This CME is S-shaped and difficult to track in later frames of difference imagery due to overlapping with other CMEs. Data gap in STEREO A difference imagery from 2023-07-31T21:53Z to 2023-08-01T05:23Z restricts measurement to two frames before leading edge of CME exits the STEREO A COR2 field of view. 1: Result 1 (2.0 AU)
