Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-05-26T18:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2023-05-26T18:24:00-CME-001 (version 1)
Source Location: S25W10
Active Region Number: 13315
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
OVR: Event partially overlaps with another CME
Source Signature Keyword:
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Very faint southern CME seen in both coronagraphs. A super faint potential source could be the simultaneous slight dimming south of AR3315 (S16W10) centered around S25W10, along with the gradual dimming NW of/enlargement of the SE coronal hole seen after 2023-05-16T15Z starting after 2023-05-26T16Z and centered around S25E30.

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 |

Very approximate analysis assuming the front-sided source and based on the best fit in swpc_cat with both coronagraphs. Fits the position of dimming south of AR 3315 as the source, but latitudes can vary from -25 to -45 or so. |

A very uncertain measurement also encompassing the very faint more eastern front, in addition to the southern more clear one (in which case it is a very complex shape CME). |
