Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-07-17T23:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-07-17T23:36:00-CME-001 (version 2)
Source Location: S25W73
Active Region Number: 13363
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
SEP: Solar Energetic Particle event
SUR: Surge-like eruption
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
EUVW: EUV Wave
Morphology Keyword:
F: Flux Rope
FS: Flux Rope and Shock Candidate
L: Loop
LS: Loop and Shock Candidate
Note: Halo CME seen primarily to the southwest in association with two separate M5.0+ class solar flares and a strong eruption from Active Region 3633 (S25W73). The eruption is proceeded by another eruption which is impressive in itself; the main eruption starting around 23:18Z as seen in SDO 131 imagery is characterized by a very large scale brightening near Active Region 3363 with rising plasma along the southeastern portion of the active region, widely and quickly moving and opening magnetic field lines seen in SDO 193/171, and a strong post-eruptive arcade signature characterized by intense, regional brightening along the southwest limb in SDO 131. Associated with SEP events at SOHO, GOES, and STEREO A.

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 |

Leading edge measurement encompassing the entire width of the CME using late frames of SOHO C2, C3 and STEREO A COR2 up to about 01:30Z. The CME moves so quickly it is not measurable in SOHO C2 in many frames. |
