Source Location: N12E45
Active Region Number: 14524

Note Keyword:

Source Signature Keyword:

FLR: Flare

Morphology Keyword:

Note: This CME is visible to the east/southeast in STEREO A COR2 and SOHO LASCO C2/C3 imagery. This event is not seen in GOES CCOR-1 imagery in real time due to a data gap starting at 2026-09-05T03:30Z. The source is an eruption and C6.4 flare from Active Region 14524 (N12E45) starting around 2026-09-05T10:30Z as seen in SDO AIA 131/171/193/304 and GOES SUVI 131/171/195/284/304 imagery.
