Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2021-10-06T17:38Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2021-10-06T17:38:00-CME-001 (version 3)
Source Location: S20W10
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
PEA: Post eruption arcade
BR: Brightening
DIM: Dimming
Morphology Keyword:
Note: This CME is likely associated with an eruption visible on the Earth-facing disk from an unnumbered active region near S20W10 as seen in SDO AIA 193 starting around 2021-10-06T15:49Z. The eruption signature exhibits a notable dimming and some subsequent field line movement. The eruption signature is also visible in STEREO A EUVI 195 near S20W50 starting around 2021-10-06T15:45Z.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.

CME Analysis M2M_CATALOG true SWPC_CAT 19.0 -8.0 300.0 S 34.0 2021-10-07T14:08Z This measurement with SWPC_CAT identified the faint outline of a partial halo in SOHO LASCO C3 imagery and a single frame from STEREO A COR2 (at 2021-10-07T09:53Z), yielding slightly higher speeds than preliminary measurements using STEREO A COR2 data from 2021-10-06T17:38Z-18:53Z when the CME is first observed to emerge from the occulting disk. 1: Result 1 (2.0 AU)
