Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2021-05-14T05:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2021-05-14T05:23:00-CME-001 (version 1)
Source Location: S22W00
Active Region Number: 12823

Note: The start time of this CME may be off due to a data gap in STEREO-A data. The source of this CME is a B4.9 class flare from Active Region 12823 starting at 2021-05-14T00:37Z, peaking at 2021-05-14T01:04Z, ending at 2021-05-14T01:31Z. The eruption is most clearly visible in SDO/AIA wavelengths 193, 171, and 94. The eruption appears as a brightening from the flare in the center of the active region with dimming occurring to the south of the active region. There is a coronal hole just south of this active region that could have deflected the CME more equatorward. The CME is best seen to the West in STEREO-A COR2 imagery. There are no visible CME features in SOHO/LASCO C2/C3 imagery.
