| Soho Lasco Note | CME first seen to the NW in STEREO A COR2 starting at 2026-07-31T08:08Z. It is also seen to the NE in GOES CCOR-1 but is covered by a real-time data gap in SOHO LASCO C2/C3. This is most likely outflow following CME: 2026-07-30T16:53Z. No additional source has been identified for this front. |
