| Soho Lasco Note | Full halo CME currently observed only in GOES CCOR-1 and somewhat blocked by its pylon. Not yet observed in other coronagraphs due to a SOHO LASCO DSN gap between 2026-06-30T20:15Z to 2026-06-30T23:45Z, and STEREO A data gap starting at 2026-06-30T19:23Z. The source is associated with an X1.1 flare |
