Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-01-20T16:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-01-20T16:12:00-CME-001 (version 2)
Active Region Number: 13190
Note Keyword:
COL: Possible collision with previous CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
F: Flux Rope
Note: CME directed mainly S in SOHO LASCO and STEREO A COR2 imagery embedded within CME: 2023-01-20T13:36Z. The source is an eruption from AR3190 located near S15W13 seen in SDO 193/304/171 with brightening at the source and opening field line movement followed by a broad area of dimming to the south, east, and west. Post eruptive arcades are also noted.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, earlier measurements are marked as false when new or more accurate measurements are made. This is a helpful flag if you would like to download only one most accurate CME analysis per CME

CME Analysis M2M_CATALOG LE true SWPC_CAT 7.0 -32.0 684.0 C 24.0 2023-01-20T19:55Z Measurement of leading edge of this particular CME with a large amount of uncertainty about the right hand bound (and thus half-width) given this CME overlaps CME: 2023-01-20T13:36Z. There was general consensus the latitude should be <-25 (deflected southward) in order to match STEREO A and SOHO observations simultaneously. 1: Result 1 (2.0 AU)
