All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2021-10-12T03:24:00-CME-001 (version 1)
Source Location: N16W30
Active Region Number: 12882
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
DIM: Dimming

Morphology Keyword:
Note: Very faint partial halo W in C2,C3 (front not seen in COR2A b/c of a large overlapping data gap from 2021-10-11T19:23Z to 2021-10-12T09:23Z). Source: eruption from AR 2882 at N16W30 seen in AIA 193/304 starting after 2021-10-12T02:03Z and associated with multiple higher B-class flares from this active region and an EUV wave seen in AIA 193.

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. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type

CME Analysis M2M_CATALOG RHB LHB true SWPC_CAT 30.0 -1.0 512.0 C 35.0 2021-10-12T09:40Z Very approximate analysis for several reasons. This 1-coronagraph SWPC CAT analysis is based on the longitude of the flares. It is possible that the CME was deflected more to the West (most of the dimming is to the West of the active region). Also, the CME was very faint in SOHO LASCO C3 difference imagery, so we made the measurement using mostly C2 imagery (with a couple of early C3 images). 1: Result 1 (2.0 AU)
