Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-02-24T13:25Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-02-24T13:25:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap
HAL: Halo CME
OVR: Event partially overlaps with another CME
SUR: Surge-like eruption
Source Signature Keyword:
OFL: Moving/Opening field lines
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: This is a wide, partial halo CME seen to the NE in SOHO LASCO C2 and C3 imagery. There is a data gap in STEREO A COR2 for this event. The source of this CME is seen beyond the NE limb in SDO/AIA 193, 171, and GOES SUVI 195, 171, and 284. The eruption is very quick and includes a single frame of a bright filament type material at 2023-02-24T12:45Z. There are clear moving/opening field lines beyond the limb (best seen in SDO/AIA 171) with a slight EUV wave on the limb to follow (best seen in GOES SUVI 284). Additional movement can be seen from AR's 13234 and 13235 on the Earth-facing disk which may be magnetically connected somehow to the eruption beyond the limb.

This is a measurement of the shock front for this CME using only SOHO LASCO imagery and source location information. Since the source is beyond the limb, there is a larger amount of uncertainty with the parameters. Specifically, the longitude may vary between -90 and -125 degrees. |

This is a measurement of the bulk of the CME using only SOHO LASCO imagery and knowledge of the source due to the data gap in STEREO A imagery. Since the source is beyond the NE limb, some uncertainty is present with these parameters. Specifically the longitude may vary between -90 to -125 degrees. The best fit based on the fronts structure matched with the fit using SWPC_CAT's lasso was used. |
1: Result 1 (2.0 AU)
