Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-17T22:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2024-04-17T22:24:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OVR: Event partially overlaps with another CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Fast, thin CME seen to the E in SOHO LASCO C2/C3. The source for this CME is uncertain, observed as some field line movement outside of the E limb starting around 2024-04-17T21:00Z in SDO AIA 171. This could correspond to some activity near AR 3645 observed in SDO AIA 171/193 that "bubbles" low at that same timestamp before a more reactive eruption starting 2024-04-17T21:55Z. However, low confidence during the CME measurement process (would be a thinner than 10 degree half-width, and no STEREO COR2A data to triangulate with) from this longitude casts some doubt on this.

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 -5.0 592.0 C 10.0 2024-04-18T04:38Z Plane-of-sky measurement using only SOHO LASCO C2/C3 due to low source confidence and lack of STEREO COR2A imagery to triangulate with due a data gap. The source could be AR 3465 around S10E25 based on EUV imagery, but this produces a <10 half-width fit. Not modeled Tony Iampietro on 2024-04-18T18:06Z
