Solar flare — 2026-10-04 06:13 UTC (B3.2)Solar flareB3.2——2026-10-04T07:24:00-CME-001GOES-P: EXIS 1.0-8.0First in pair of eruptive flares from AR 14546, followed immediately by a B9.3 class flare peaking at 2026-10-04T06:30Z. These two flares are in close succession, but visually separable in SDO AIA 131 and in their respective field line movements in SDO AIA 171.

These two flares are in close succession, but visually separable in SDO AIA 131 and in their respective field line movements in SDO AIA 171.

Coronal mass ejection — 2026-09-24 14:45 UTCCoronal mass ejection—493 km/s1—GOES: CCOR-1, STEREO A: SECCHI/COR2CME observed to the SW in GOES CCOR-1 and S in STEREO A COR2, overlapping with a slow, wide streamer blowout beginning ~2026-09-23T20:12Z (itself measuring ~176 km/s). Not observed in SOHO LASCO C2/C3 due to a real-time data gap. The source is field line movement and small shifting of a coronal hole boundary best observed only in GOES SUVI 284 starting ~2026-09-24T14:02Z, tracing on-disk around S35W70 in proximity to a large southern coronal hole.
Coronal mass ejection — 2026-09-25 17:45 UTCCoronal mass ejection—462 km/s1—GOES: CCOR-1, SOHO: LASCO/C3Faint CME that looks to consist of two loops moving together as one. It is seen faintly to the NE in GOES CCOR-1 and SOHO LASCO C3 difference imagery, moving in the footsteps of 2026-09-25T11:09Z CME. No coronal signatures have been found for this event, so it is likely far-sided.
Coronal mass ejection — 2026-09-25 20:45 UTCCoronal mass ejection—460 km/s1—GOES: CCOR-1, SOHO: LASCO/C3A narrow CME seen to the NE in GOES CCOR-1/SOHO LASCO C3 with a pointed front. It is not seen in STEREO A COR2 and SOHO LASCO C2 currently because of a data gap. No coronal signatures have been found for this CME in EUV imagery, except for possibly some movement of field lines to the NE seen in GOES SUVI 284.
Coronal mass ejection — 2026-09-26 20:00 UTCCoronal mass ejection—336 km/s1—GOES: CCOR-1, SOHO: LASCO/C3A minor faint CME seen to the NE in GOES CCOR-1 and SOHO LASCO C3, and not seen in STEREO A COR2 coronagraph. No source has been found in EUV imagery for this CME, so it is likely far-sided.
Coronal mass ejection — 2026-10-09 00:45 UTCCoronal mass ejection—293 km/s1—GOES: CCOR-1CME faintly seen to the east in GOES CCOR-1 imagery. There is a data gap in SOHO LASCO C2/C3 imagery starting at 2026-10-09T00:48Z and a data gap starting in STEREO A COR2 at 2026-10-09T00:53Z. The source is likely beyond the E limb as seen in available EUV imagery, as slow moving field lines are visible on the E limb in SDO AIA 193 and GOES SUVI 284 imagery starting as early as 2026-10-08T18:30Z.
Coronal mass ejection — 2026-10-09 07:15 UTCCoronal mass ejection—391 km/s1—GOES: CCOR-1CME seen to the NW in GOES CCOR-1 imagery. There is a data gap in SOHO LASCO C2/C3 and STEREO A COR2 at the time of this CME. The potential source is unclear, but is likely an eruption from AR 14547 (approximately N15W90) starting around 2026-10-09T06:30Z, best seen as moving/opening field lines in SDO AIA 193 and GOES SUVI 284 imagery.
Coronal mass ejection — 2026-10-09 08:00 UTCCoronal mass ejection—270 km/s1—GOES: CCOR-1CME visible to the NNW in GOES CCOR-1 imagery. There is no SOHO LASCO C2/C3 or STEREO A COR2 data available during this time, with a data gap in SOHO imagery starting at 2026-10-09T00:48Z and no STEREO A COR2 data available since 2026-10-09T01:09Z. The source for this CME is not found in available EUV imagery.

  • DONKI information is supplied for research and analysis. It is not an operational emergency-warning service: NOAA's Space Weather Prediction Center (swpc.noaa.gov) is the official US source of space weather forecasts and warnings.
  • Observations, analyses (a CME can have several, with the one DONKI marks most accurate), model predictions (WSA-ENLIL) and notifications are shown as such, in their original units and classifications. No combined severity score is computed.
  • Times are UTC as supplied. DONKI revises entries; the look-back window is re-read on every refresh.
