Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2022-01-20T22:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2022-01-20T22:12:00-CME-001 (version 1)

DIM: Dimming
Morphology Keyword:
Note: This faint/narrow CME is likely associated with a gradual dimming visible toward the SE limb of STEREO A-facing disk seen in STA EUVI 195 (near S50E75) starting around 2022-01-21T20:00Z. Opening field lines likely associated with this CME are visible toward the SE limb of the Earth-facing disk as seen in SDO AIA 171 starting around the same time.

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 LE true StereoCAT -99.0 -22.0 343.0 S 11.0 2022-01-21T10:50Z This StereoCAT measurement matched the faint leading edge of the CME seen in SOHO LASCO C3 and STEREO A COR2 white light coronagraph imagery. Measurements made with SWPC_CAT yielded similar CME parameters, noting some uncertainty in speed due to the CME's diffuse leading edge. 1: Result 1 (2.0 AU)
