Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2022-03-25T06:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2022-03-25T06:12:00-CME-001 (version 2)
Source Location: S19E36
Active Region Number: 12974
Note Keyword:
Faint: Faint event; may affect type assignment
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
EUVW: EUV Wave
Morphology Keyword:
LS: Loop and Shock Candidate
Note: This CME is first visible to the East in SOHO LASCO C2/C3 and to the SW in STEREO A COR2. As the CME propagates out of the field of view, the halo feature becomes more clear in both SOHO and STEREO A coronagraphs. The source of this CME is the M1.4 class flare from AR12974 (~S19E36) that peaked at 2022-03-25T05:26Z (based off of GOES-17 data). The flare and associated EUV wave (which at least in SDO AIA is mostly West-directed) are clearly seen in SDO/AIA 193, 171, 211, and 94. There is a data gap in STEREO A EUVI 195 during this event, so we do not see the EUV wave in STEREO A, but a change in the associated Active Region is visible after the data gap.

These parameters are based off of the best fit between the SOHO LASCO C2/C3 and STEREO A COR2 coronagraphs. The bulk of the CME seen from SOHO LASCO C2/C3 was matched with the black/white boundary front to the SW in STEREO A COR2. It is possible this CME may have higher speeds if measuring the shock front. Analysis had speeds ranging between 500 km/s and 700 km/s depending on the parameters used (longitude, latitude, and half-width) as well as the features tracked. |

This separate analysis has been performed for the shock of the CME seen as an almost full halo in SOHO LASCO C2/C3; it was possibly also traced as a very faint feature to the West in COR2A. Note that the bulk of the CME seems to have gone in a more Eastern direction, which corresponds to its source location (AR12974). This analysis for the shock is based on fitting the almost full halo in LASCO with the super faint Western feature in COR2A, using SWPC CAT and does not take into consideration the source location of this CME which was further East. |
