Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-07-30T04:30Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2025-07-30T04:30:00-CME-001 (version 2)
Source Location: S21W17
Active Region Number: 14157
Note Keyword:
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
O: Other
Note: Super faint CME with a fuzzy front to the SE seen very faintly in STEREO A COR2 running difference imagery. It is possibly that the faint fuzzy front of the same CME might be seen to the SW in SOHO LASCO C2, partially overlapping with the somewhat brighter 2025-07-30T03:36Z CME. The CME is not seen in C3 and GOES CCOR-1. A possible source could be a filament eruption near AR 14157 (S21W17) best seen (although still very faintly) in GOES SUVI 304 and STEREO A EUV 304 after 2025-07-30T02:45Z.

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 |

An uncertain one-coronagraph analysis with STEREO A COR2 based on the location of the possible source (AR 4157) and on a very faint front in STEREO A COR2 coronagraph. |

An extremely uncertain analysis, based on the location of the possible source (filament eruption in AR 4157) and on the fit of two very faint uncertain fuzzy fronts in C2 and COR2A coronagraphs. The speed of the CME obtained by this method ranges from 400 to 600 km/s. |
