Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-05T01:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-09-05T01:36:00-CME-001 (version 1)
Source Location: N29W05
Active Region Number: 14207
Note Keyword:
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FLR: Flare
Morphology Keyword:
F: Flux Rope
Note: Narrow flux rope CME seen to the NNW in SOHO LASCO C2/C3 and N in STEREO A COR2. Obstructed by Earthshine in GOES CCOR-1. Source is an eruption centered at N29W05 and an M1.4 flare (N28W00), both from AR 14207 (centered at N29E10). Brightening and ejecta can be seen in SDO AIA 193 starting at 2025-09-05T01:09Z. SDO AIA 304 shows ejecta with heavy northward and slight westward deflection. This eruption is in close proximity to a small coronal hole centered at N21W05 as seen in SDO AIA 193, which is directly adjacent and to the southwest of AR 14207; this very likely contributed to the strong northwestward deflection of this eruption.

Best fit measurement using several frames of SOHO LASCO C3 and STEREO A COR2. This eruption is in close proximity to a small coronal hole centered at N21W05 as seen in SDO AIA 193, which is directly adjacent and to the southwest of AR 14207 (centered at N29E10); this very likely contributed to the strong northwestward deflection of this eruption. |
