Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-15T17:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-06-15T17:48:00-CME-001 (version 1)
Source Location: S12W90
Active Region Number: 14105
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
L: Loop
Note: Extremely faint loop CME seen to the W in SOHO LASCO C2 for a few frames before becoming diffuse. This CME is not visible in SOHO LASCO C3, STEREO A COR2, or GOES CCOR-1 due to the faintness of the leading edge. Source is a series of gradually-rising loops of field lines seen ejected from on or near the West limb in GOES SUVI 284 starting at 2025-06-15T17:08Z. A continuing outflow of other rising loops from this same location can be seen continuously and slowly lifting off through at least 2025-06-15T20:00Z. A minor brightening and eruption from S12W90, possibly the northern portion of AR 14105 (S15W80, at the time) can be seen at 2025-06-15T18:03Z in SDO AIA 171/193 as well as associated field line opening. It is very likely that this is the source for one of the subsequent outflows. Brightening and a ribbon of material can be seen in GOES SUVI 304, as well as a rising loop, but it appears that the ribbon may not have fully ejected and fell back to the surface.

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 |

Measurement using only SOHO LASCO C2 frames since the leading edge becomes diffuse before reaching the edge of the C2 field of view. Measurement based on best fit in SOHO LASCO C2 and the location of the source at W90 as identified in available UV imagery. |
