Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-07-16T04:42Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-07-16T04:42:00-CME-001 (version 1)
Note Keyword:
COL: Possible collision with previous CME
GAP: Data gap
HAL: Halo CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
EUVW: EUV Wave
Morphology Keyword:
LS: Loop and Shock Candidate
Note: CME bulk seen to the west, and CME shock seen as a full halo in SOHO LASCO C2, C3 and STEREO A COR2 coronagraphs. Source is widely moving/opening field lines beyond the NW limb seen in GOES SUVI 171/284 first seen at 2023-07-16T04:31Z. Data gap in SOHO LASCO C3; cadence reduced to 1 frame per 3 hours.

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 SWPC_CAT 120.0 5.0 1220.0 O 51.0 2023-07-16T07:34Z The leading edge of this CME is only visible for a few frames in SOHO LASCO C2 and STEREO A COR2 due to its speed. SOHO LASCO C3 was experiencing a reduced cadence of one frame per three hours. Unable to obtain reliable measurement from limited C3 difference imagery, so best fit was made using SOHO LASCO C2 and STEREO A COR2 only. 1: Result 1 (2.0 AU)
