Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-05-30T17:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-05-30T17:12:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
Morphology Keyword:
L: Loop
LS: Loop and Shock Candidate
U: Unknown
US: Unknown and Shock Candidate
Note: Faint, slow, loop-like CME seen to the west-northwest in SOHO C2, C3 and appearing slightly brighter in STEREO A COR2 in the same direction. Measurements indicate some confidence in an Earth-facing source on the Sun between longitudes 20 and 30 degrees, but the source is unclear. Possibly associated with brightening and dimming seen on the Earth facing disk early on 2023-05-30 near N00W40, or with a deflected minor eruption associated with AR3319.

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 26.0 7.0 311.0 S 30.0 2023-05-31T04:38Z Speculative measurement using SOHO and STEREO A to triangulate the source; there is medium confidence in the speed and longitude parameters, though the source was undetermined/unclear. The CME is difficult if not impossible to associate with/match with far-side activity using triangulation. 1: Result 1 (2.0 AU)

CME Analysis M2M_CATALOG LE false SWPC_CAT 27.0 11.0 256.0 S 41.0 2023-05-31T07:04Z Measurement which considers a slower/wider CME incorporating the front seen to the north and west. 1: Result 1 (2.0 AU)
Earth = 2023-06-04T07:00Z (PE: 9.9 h)
OSIRIS-REx = 2023-06-06T03:00Z
