Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-26T00:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-03-26T00:48:00-CME-001 (version 1)
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: Faint, thin CME observed to the SW in SOHO LASCO C2/C3 and GOES CCOR-1, not observed in STEREO A COR2 due to a data gap. The CME is barely a half width of 10 degrees, perhaps slightly smaller. The source is observed as field line movement over the SW limb beginning at 2026-03-26T23:40Z in GOES SUVI 171/195/284, likely originating from former AR 14392 which is around W100-W105 at this time, although direct observations of the source are not possible without STEREO A EUVI to confirm longitude.

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 |

Single spacecraft 3D analysis using W100 as an estimation of the source location of former AR 14392 which has rotated around the SW limb, as such the longitude could vary W95-W105. CME half width is barely 10 degrees, perhaps a little smaller. |
1: Result 1 (2.0 AU)
2: Result 2 (5.5 AU)
