Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-10-31T00:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-10-31T00:36:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Faint loop CME seen to the SE in SOHO LASCO C2/C3 and GOES CCOR-1, and to the SE in STEREO A COR2. Source is likely field line movement beyond the SE limb as seen in GOES SUVI 284 starting at 2025-10-31T23:57Z, at an apparent latitude of about S20 but with heavy southward deflection; this field line movement occurs just south of and nearly simultaneous with a much larger eruption which was beyond the East limb.

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 using candidate source location seen in available UV imagery and best fit between several frames of STEREO A COR2 and a few frames from SOHO LASCO C2/C3 and GOES CCOR-1. The leading edge is partially obstructed by the pylon in both SOHO LASCO C3 and in GOES CCOR-1. The leading edge is most clearly seen in STEREO A COR2. |
