Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-05-11T02:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-05-11T02:36:00-CME-001 (version 2)
Note Keyword:
3P: 3-part structure CME
FOV: Front Bright front; may be evidence of pileup
Ha: Bright emission (likely H-alpha emission)
OFL: Outflowing material at the back of the CME
SB: Streamer Blowout following CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Textbook "lightbulb" 3-part CME seen to the E in all coronagraphs. The source is uncertain, and may be related to a streamer blowout observed as some slow field line movement/loop opening on the NE limb that begins as early as 2024-05-11T21:12Z and lasting for several hours, best observed in SDO AIA 171/193/211.

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

CME Analysis M2M_CATALOG LE true Plane-of-sky NONE 13.0 485.0 S 38.0 2024-05-11T13:07Z Plane-of-sky measurement with only SOHO LASCO C3, due to acceleration in frames outside of C2's FOV alongside the uncertain source. The longitude for this CME is likely near the limb regardless, potentially E110-E80. Not modeled Tony Iampietro on 2024-05-11T20:23Z
