Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-07-17T01:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-07-17T01:23:00-CME-001 (version 1)
Note Keyword:
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:
US: Unknown and Shock Candidate
Note: Full-halo CME seen to the northwest in STEREO A COR2 and in SOHO LASCO C2/C3 (Short data gap in C2 from 2023-07-17T00:51Z to 2023-07-17T01:33Z. Reduced cadence in C3.) The source for this eruption is beyond the northwest limb. A very large piece of ejecta (spans an apparent 30 degrees of latitude or so) is seen flying off to the northwest from beyond the NW limb as seen in GOES SUVI 304 starting at 2023-07-17T00:49Z. Widely opening field lines also seen on the NW limb in GOES SUVI 284/195/171 starting at 2023-07-17T00:51Z.

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 |

Measurement made attempting best fit between coronagraphs. Reduced cadence in SOHO LASCO C3 results in low resolution difference imagery. The few frames that the leading edge of the CME is in C2's FOV are corrupt, rendering C2 difference imagery unusable for reliable measuring. |
