  • Source:
  • Region:
  • Note: No clear source has been found but around 2024-11-28T18:17Z in GOES SUVI 171, 195, 284, there is an area of slight field lines movement close to the southeast limb.

  • Catalog: M2M_CATALOG
  • Start: Thu, 28 Nov 2024 02:12:00 +0000
  • Source:
  • Region:
  • Note: A slow CME that is very slow to develop (speeds up a little bit with time). Its likely source is a small eruption visible near the eastern limb in GOES SUVI 171, 193, 285, 304 imagery starting around 2024-11-28T01:00Z. The flux rope for this CME is later clearly seen in coronagraph.

  • Catalog: M2M_CATALOG
  • Start: Wed, 27 Nov 2024 19:48:00 +0000
  • Source:
  • Region:
  • Note: This CME is visible to the east in SOHO LASCO C2, C3, and one frame of STEREO A COR2 imagery. The source is a filament eruption visible on or just beyond the eastern limb in GOES SUVI 304 starting around 2024-11-27T19:26Z (possible flare trigger to start with a region just beyond the limb).

  • Catalog: M2M_CATALOG
  • Start: Wed, 27 Nov 2024 19:24:00 +0000
  • Source: S16E08
  • Region: 13906
  • Note: Southeastward partial halo CME with the likely source a filament eruption seen in GOES SUVI 304 and 284 starting around 2024-11-27T18:45Z extending southeastwards from Active Regions 13905 (S09E01) and 13906 (S16E08). The CME also has a second, following front - a loop seen in SOHO LASCO C2 at 2024-11-27T20:36Z. Only one frame for this CME is available in STEREO A COR2 because of an extensive data gap.
