Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-22T12:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-04-22T12:36:00-CME-001 (version 1)
Source Location: S19W45
Active Region Number: 13638
Note Keyword:
DFL: Likely deflection of the event within the FOV
GAP: Data gap
Ha: Bright emission (likely H-alpha emission)
OFL: Outflowing material at the back of the CME
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: CME seen to the S in all coronagraphs but mostly SOHO LASCO C2/C3, due to a STEREO data gap. The source is an eruption from AR 3638 at S19W45, coupled with an C5.9-class flare which peaked at 2024-04-22T12:12Z best seen in SDO AIA 131. Also observed as the flare, field line movement, and dark filament material outflowing along field lines in SDO AIA 171/193/211/304. The eruption is observed, and corroborated with swpc_cat measurements, to deflect south and east of this source lat/lon.

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 made with only SOHO LASCO C3 and late STEREO COR2A imagery, as the CME was deflecting in C2 and not reliably trackable until it settled in the C3 FOV. Initial lat/lon were based on the observed EUV source, and the deflection to the south and east was roughly estimated on the behavior of very similar CME 2024-04-22T06:12Z which featured all coronagraphs for triangulation. As such, some variance in the true lat/lon may be present with only one coronagraph measuring this fairly central longitude, with good confidence in the high southern latitude out of the ecliptic plane. |
