Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-21T22:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-04-21T22:12:00-CME-001 (version 1)
Source Location: S19W37
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
EUVW: EUV Wave
Morphology Keyword:
F: Flux Rope
Note: CME seen to the S in SOHO LASCO C2/C3 only, due to a STEREO data gap. The source is an eruption from AR 3638 at S19W37, coupled with an M3.4-class flare which peaked at 2024-04-21T21:52Z 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, with a notable large EUV wave in SDO AIA 193 as well. The eruption is observed, and corroborated with swpc_cat measurements, to deflect south and east of this source lat/lon.

Bulk measurement. Measurement made with only SOHO LASCO C3 imagery, as the CME was deflecting in C2 and not reliably trackable until it settled in the C3 FOV, alongside a data gap in STEREO COR2A. 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. |

Shock measurement of a wider and faint, but noticeable feature traveling with the bulk front (which tracks with the observed EUV wave in SDO). Made with only SOHO LASCO C2/C3 imagery due to a data gap in STEREO COR2A, and as such some variance in the true lat/lon may be noted given the single coronagraph measurement. Initial lat/lon were based on the observed EUV source, and found a good fit near this with some southward deflection. |
