  • Catalog: M2M_CATALOG
  • Start: Tue, 17 Dec 2024 13:25:00 +0000
  • Source:
  • Region:
  • Note: Faint CME visible to the east in SOHO LACSO C2/C3, not seen in STEREO A COR2 due to a data gap starting at 2024-12-17T11:36Z. The source is not clearly visible, and it may be farsided. Field line movement may be seen near the limb in GOES SUVI 171/195/284 from approximately 2024-12-17T07:00Z to 13:00Z, but no clear eruption is seen and no source location can be determined.

  • Start: Tue, 17 Dec 2024 09:53:00 +0000
  • Source:
  • Region:
  • Note: CME faintly visible to the southwest in STEREO A COR2. This CME not was clearly seen in any available SOHO LASCO C2/C3 imagery. The source was also not found. The CME fades away after a few frames of STEREO A COR2 imagery.

  • Catalog: M2M_CATALOG
  • Start: Tue, 17 Dec 2024 08:24:00 +0000
  • Source:
  • Region:
  • Note: CME visible to the SE in SOHO LASCO C2/C3 and STEREO A COR2. The source is a filament eruption that appears to have a footpoint located at approximately S40E40 and a footpoint that wraps beyond the east limb as seen in available GOES SUVI imagery. Filament liftoff is seen starting at 2024-12-17T06:40Z in GOES SUVI 304. Dimming and opening field lines are also visible in GOES SUVI 195 and opening field lines are seen in GOES SUVI 284. The eruption is also visible in STEREO A EUV 195 and 304 imagery.

  • Catalog: M2M_CATALOG
  • Start: Tue, 17 Dec 2024 04:36:00 +0000
  • Source: S10E80
  • Region:
  • Note: CME visible to the east in SOHO LASCO C2/C3 and STEREO A COR2. The source is an eruption starting at 2024-12-17T03:52Z in GOES SUVI 304 around S10E80. Opening field lines are also visible in GOES SUVI 171/195/284. The eruption is also visible in STEREO A EUV 195/304.

  • Catalog: M2M_CATALOG
  • Start: Mon, 16 Dec 2024 21:48:00 +0000
  • Source: N32E80
  • Region:
  • Note: Minor, relatively slow CME seen to the northeast in SOHO LASCO C2 along a minor streamer. Associated with a minor eruption near N32E80 as evidenced by opening field lines seen best in GOES SUVI 284.

2024-12-16T18:48:00-CME-001

  • Catalog: M2M_CATALOG
  • Start: Mon, 16 Dec 2024 18:48:00 +0000
  • Source:
  • Region:
  • Note: Minor and relatively faint CME seen to the southeast in SOHO LASCO C2 and not seen well in STEREO A COR2 data. Likely associated with moving field lines from an active region rotating onto the Earth-facing disk at perhaps a longitude between -80 and -90 degrees, as seen in GOES SUVI 284.
