Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-05-26T22:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-05-26T22:36:00-CME-001 (version 1)
Source Location: S30E53
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Very faint partial halo CME observed in SOHO LASCO C2 and GOES CCOR-1, also in LASCO C3 obscured heavily by the pylon (and difficult to observe outside running difference imagery in all). STEREO A COR2 in a data gap at this time. The source may be some field line movement and breaking loops observed around 2026-05-26T21:39Z to the SE only in GOES SUVI 284, tracing to an approximate source on-disk around S30E53 (and could vary slightly, due to the brightness of this cluster of regions in SUVI 284).

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 |

3D SOHO LASCO C2 and GOES CCOR-1 tracking using the approximate source ~E53 and using the partial halo shape for the width. Due to the faintness of this front and no COR2A to triangulate, the latitude, longitude, and width could vary. |
