  • Catalog: M2M_CATALOG
  • Start: Fri, 27 Dec 2024 21:12:00 +0000
  • Source:
  • Region:
  • Note: Super faint narrow outflow to the SE. The source could be a narrow ejecta in GOES SUVI 304 at 21Z and opening/movement of field lines behind the SE limb seen in SUVI 284 around 20:59Z (but this eruption could be the source of the 22:00Z or 22:12 CME alternatively).

  • Catalog: M2M_CATALOG
  • Start: Fri, 27 Dec 2024 07:36:00 +0000
  • Source:
  • Region:
  • Note: This CME is visible to the southeast in SOHO LASCO C2/C3 and to the south in STEREO A COR2 imagery. The source is likely far-sided as there are no relevant source signatures visible on the Earth-facing disk at the time of this event.

  • Catalog: M2M_CATALOG
  • Start: Fri, 27 Dec 2024 06:36:00 +0000
  • Source: S05E65
  • Region:
  • Note: This CME is visible to the east in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is likely an eruption centered near S05E65 seen in GOES SUVI 131, 171, 195, 304 imagery starting around 2024-12-27T05:50Z. A subsequent opening of field lines is visible over the eruption site in GOES SUVI 195 and 284 imagery around this time as well.

  • Catalog: M2M_CATALOG
  • Start: Fri, 27 Dec 2024 04:39:00 +0000
  • Source:
  • Region:
  • Note: This CME is visible to the southeast in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is likely related to a faint opening of field lines observed beyond the southeast limb in GOES SUVI 131, 171, 195, 284 imagery starting around 2024-12-27T04:30Z.

  • Source:
  • Region:
  • Note: This CME is visible to the southeast in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is likely related to a fast opening of field lines observed beyond the southeast limb in GOES SUVI 131, 171, 195, 284 imagery starting around 2024-12-27T01:00Z.

2024-12-26T19:12:00-CME-001

  • Catalog: M2M_CATALOG
  • Start: Thu, 26 Dec 2024 19:12:00 +0000
  • Source: N25E35
  • Region:
  • Note: This CME is seen as a faint front to the NE in SOHO LASCO C2 and C3 imagery, not visible in STEREO A COR2 imagery due to a data gap. The potential source is a filament eruption near AR13938 starting around 2024-12-26T18:40Z. The filament stretches between -30 and -45 degrees longitude and 20 to 30 degrees north in latitude as seen in GOES SUVI 304.
