Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-08T12:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-05-08T12:24:00-CME-001 (version 1)
Source Location: S20W11
Active Region Number: 13664
Note Keyword:
COL: Possible collision with previous CME
DFL: Likely deflection of the event within the FOV
DPL: CME exhibits dimpled front
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FLR: Flare
DFLR: Double ribbon flare
OFL: Moving/Opening field lines
BR: Brightening
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Earth-directed full halo seen in all coronagraphs. The source is a large eruption from AR 3664, which included a long-duration M8.6 flare (S22W11) which peaked at 2024-05-08T12:04Z best seen in SDO AIA 131. An EUV wave and field line movement is observed in SDO AIA 94/131/171/211 with some surface brightening in SDO AIA 304. This flare+CME combo resulted in a small rise in protons observed at SOHO and GOES, but not enough for a threshold crossing. The start time used here is when the shock front emerges, with the brighter bulk front emerging ~2024-05-08T13:00Z.

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 |

Preliminary BULK measurement made using both coronagraphs, with limited imagery due to a current gap between SOHO downlinks due to resume at T17:15Z today and recency of the front emerging in all imagery. Source of S22W11 (the M8.6-Class flare) used as a basis, finding a good triangulation between SOHO and STEREO with some NE deflection. |
