Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-02-02T17:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C3
Activity ID: 2024-02-02T17:09:00-CME-001 (version 2)
Source Location: S16E52
Active Region Number: 13571
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
O: Other
Note: Faint CME seen to the SE in all coronagraphs (missed by SOHO LASCO C2, but seen in C3). Source is one or two eruptions together from AR 3571; one beginning around 2024-02-02T15:18Z and another shortly after around 2024-02-02T16:27Z. Both eruptions have unique flares best seen in SDO AIA 131, peaking at C3.0 at 2024-02-02T15:34Z and C3.1 at 2024-02-02T16:32Z. Both eruptions eject filament material seen well in SDO AIA 304 and GOES SUVI 304 alongside dimming, field line movement, and an EUV wave in SDO AIA 171/193/211 that may combine to contribute to this front. This CME is followed by a much slower yet brighter front that may be from the same source region, measuring <200 km/s.

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 |

Measured using the source of AR 3571 at the time of eruption and triangulation between SOHO LASCO C3 and STEREO COR2A, noting some southward deflection to get a measured longitude close to the observed longitude in SDO. SOHO LASCO C2 did not observe this event due to a data gap. |
