Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-17T13:16Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-02-17T13:16:00-CME-001 (version 8)
Note Keyword:
DPL: CME exhibits dimpled front
FOV: Front Bright front; may be evidence of pileup
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Bright partial halo CME in the southeast, with the source behind the SE limb seen in AIA 304/171/193 and GOES SUVI 304 as a large prominence eruption directed southward, bright ejecta likely with H-alpha emission (mostly in the south) and filametary structures, and a significant restructuring of magnetic field behind the southeast limb seen in AIA 193/171. There is even a little bit of an EUV wave seen on the Earth facing disk in the very SE in AIA 193 and 171. There is a second outflow/front seen in SOHO LASCO C3 around 15:08Z, eventually merging with the original front.

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 |

Approximate measurement of wider fainter shock of this CME based on fit in one coronagraph (SOHO LASCO). No STEREO A COR2 imagery is available for this event at the time because of a data gap from 2024-02-17T11:55Z. |

Updated analysis of bulk based on later SOHO LASCO C3 imagery, focuses on the likely wider bulk of the CME including previously excluded NE feature of the CME. One coronagraph analysis since no STEREO A coronagraph imagery available because of a large data gap.
Note that the second outflow/front seen in SOHO LASCO C3 around 15:08Z also measured with similar parameters and was not separately added to the database. |

Very approximate analysis with early SOHO LASCO imagery focusing on a narrower brighter portion of this CME (a likely bulk) with one (SOHO) coronagraph based on the likely source as Active Region 13575 which is at approximately -145 deg longitude. |
