Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-09-01T12:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-09-01T12:23:00-CME-001 (version 1)
Source Location: S25E90
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
Source Signature Keyword:
PEA: Post eruption arcade
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Bright CME seen to the southeast in SOHO LASCO C2/C3 and STEREO A COR2. Source is a large eruption on the SE limb seen as brightening starting at 2024-09-01T11:06Z in SDO AIA 131, ejection of material at 11:18Z in SDO AIA 304, rapidly opening field lines seen beyond the limb starting at 11:30Z in SDO AIA 171/193. Slow rise and eventual ejection of two overlapping flux rope loops from the southeast limb seen starting as early as 2024-09-01T08:08Z in GOES SUVI 304. Long-duration M5.5 flare associated with brightening from post-eruptive arcades that spanned from S20-S30, as seen in SDO AIA and GOES SUVI imagery.

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 |

Updated StereoCAT analysis using SOHO LASCO C3 and STEREO A COR2. The shock measurement yielded similar parameters, but a wider half-width. |
1: Result 1 (2.0 AU)

Measurement of bright leading edge using source location as seen in EUV imagery and best fit between SOHO LASCO C3 and STEREO A COR2 imagery. Several frames of C3 and COR2A were able to be used. |
1: Result 1 (2.0 AU)
2: Result 2 (5.5 AU)
