Region numbers here are DONKI's full five-digit NOAA numbers. NOAA's daily region report, above, publishes the last four digits of the same number — so DONKI's region 14518 and the report's region 4518 are one region. Neither provider's value is rewritten.

DONKI is NASA CCMC's analyst-curated research catalogue, and CCMC states that its real-time contents “should be considered only as prototyping quality and in research context”. Curation lags events by hours, so an empty list here means nothing has been catalogued yet — not that nothing happened. For operational status, read the SWPC alerts above.

• 395 km/shalf-angle 16°first seen 2026-09-15 08:36 UTC · DONKI record

  Very faint CME/outflow with a fuzzy, unclear front seen to the NE in early images of SOHO LASCO C2 only. It is not seen in SOHO LASCO C3, STEREO A COR2 and GOES CCOR-1, likely because of its faintness. No source for this feature has been found in EUV imagery.

• 461 km/shalf-angle 19°first seen 2026-09-14 17:24 UTC · DONKI record

  CME observed to the NW in SOHO LASCO C2/C3 and GOES CCOR-1, likely not observed in STEREO A COR2 either due to faintness or a data gap starting at 2026-09-14T18:53Z before it becomes visible. The source is far-sided over the NW limb, observed in SDO AIA 171/193 starting around 2026-09-17T15:48Z as slow, wide field line movement. More directly observed in STEREO A EUVI 195/304 starting as early as 2026-09-14T14:55Z, as brightening and dimming centered around an estimated N30W115 in the NW disk near former Active Regions 14523 and 14521.

• 744 km/shalf-angle 24°S11W38first seen 2026-09-14 11:08 UTC · DONKI record

  CME first seen to the E in STEREO A COR2 starting at 2026-09-14T11:08Z. It is also seen to the W in GOES CCOR-1. This CME is covered by a data gap in SOHO LASCO C2/C3 in real time. The source of this CME is an eruption centered around AR 14528 (S11W38) best seen in GOES SUVI 284 beginning around 2026-09-14T10:00Z. Field line movement can be seen accompanied by brightening and ejecta. Post-eruptive arcades can also be seen in SDO AIA 193. There seems to be a northwestward deflection from the location of the source. There are two large coronal holes (a northern and a southern one) nearby, possib…[truncated]

• 645 km/shalf-angle 22°S10W10first seen 2026-09-13 21:12 UTC · DONKI record

  Faint CME first seen to the West by SOHO LASCO C2 beginning at 2026-09-13T21:12Z, as well as by SOHO LASCO C3 and GOES CCOR-1 in later frames. This event is not seen in STEREO A COR2 due to a data gap which began at 2026-09-13T19:23Z. The source of this CME is likely outflow following an earlier filament eruption beginning at 2026-09-13T18:48Z centered at approx. S10W10 as seen in SDO AIA 193 and 304. This CME is likely deflected to the NW due to proximity to a large coronal hole.

• 1305 km/shalf-angle 23°S10W10first seen 2026-09-13 19:48 UTC · DONKI record

  CME first seen to the West by SOHO LASCO C2 beginning at 2026-09-13T19:48Z, as well as by SOHO LASCO C3 and GOES CCOR-1. This CME is not seen in STEREO A COR2 due to a data gap beginning at 2026-09-13T19:23Z. The source of this event is a center disk filament eruption beginning at approx. 2026-09-13T18:48Z best seen in SDO AIA and STEREO A COR2 304, centered at approx. S10W10. This filament appears to be deflected towards the NW, which is supported by dimming seen moving towards the NW, expanding to approx. N10W30 as seen in SDO AIA 193. This eruption is close to a large coronal hole which may…[truncated]

• 295 km/shalf-angle 22°first seen 2026-09-13 10:23 UTC · DONKI record

  CME first seen to the W in STEREO A COR2 starting at 2026-09-13T10:23Z and fades before leaving the FOV of STEREO A COR2. This feature is not see in SOHO LASCO C2/C3 or in GOES CCOR-1. The source is likely related to field line movement seen beyond the WNW limb in STA EUVI 195 beginning after 2026-09-13T08:00Z.

• 319 km/shalf-angle 10°first seen 2026-09-13 07:48 UTC · DONKI record

  Very narrow CME first seen to the SW in SOHO LASCO C2 starting around 2026-09-13T07:48Z. It is first seen part way into the FOV of SOHO LASCO C2 and is also seen in SOHO LASCO C3 and GOES CCOR-1 but not in STEREO A COR2. The source may be related to minor field line movement beyond the SW limb best seen in SDO AIA 171 beginning around 2026-09-13T06:00Z.

• 403 km/shalf-angle 19°first seen 2026-09-13 01:24 UTC · DONKI record

  CME first seen to the W in SOHO LASCO C2 starting at 2026-09-13T01:24Z. It is also seen to the W in SOHO LASCO C3. This CME is mostly obscured by Earthshine in GOES CCOR-1 and is not seen in STEREO A COR2. There is no definitive source candidate, but the source may be related to some minor activity in a filament structure over the W limb best seen in GOES SUVI 304 beginning around 2026-09-13T22:30Z.

• 337 km/shalf-angle 13°first seen 2026-09-12 08:38 UTC · DONKI record

  Faint CME first seen to the WSW in STEREO A COR2 starting at 2026-09-12T08:38Z. This feature is only seen in STEREO A COR2. No good source candidate can be seen in SDO AIA or STA EUVI, so the source is most likely far-sided.

• 268 km/shalf-angle 10°first seen 2026-09-12 01:26 UTC · DONKI record

  Slow, narrow feature first seen to the NNW in SOHO LASCO C2. Is it only seen in SOHO LASCO C2 and fades before leaving the FOV of SOHO LASCO C2. The source is possibly related to some rising filamentary structures best seen in GOES SUVI 304. This activity begins several hours prior to the CME start time and persists after.

• 350 km/shalf-angle 10°first seen 2026-09-11 23:12 UTC · DONKI record

  CME first seen to the NNW by SOHO LASCO C2 beginning at 2026-09-11T23:12Z. The source of this event is a small breaking of a prominence along the NNW limb along with faint field line opening seen in GOES SUVI 284 and 304 beginning at approx. 2026-09-11T22:50Z.

• 428 km/shalf-angle 28°first seen 2026-09-11 17:12 UTC · DONKI record

  Faint CME first seen to the NW by SOHO LASCO C2 beginning at 2026-09-11T17:12Z, as well as by SOHO LASCO C3 in later frames. This CME is too faint to be seen in STEREO A COR2 and is obscured by the pylon in GOES CCOR-1. The source of this event is faint field line movement seen beyond the NW limb in SDO AIA 171 beginning at approx. 2026-09-11T15:48Z.

• 340 km/shalf-angle 10°first seen 2026-09-11 16:12 UTC · DONKI record

  Faint, narrow CME first seen to the SE by SOHO LASCO C2 beginning at 2026-09-11T16:12Z, as well as by STEREO A COR2 and GOES CCOR-1 in later frames. This CME is obscured by the pylon in SOHO LASCO C3. The source oft this event is a very minor filament eruption seen along the SE limb in SDO AIA 304 beginning at approx. 2026-09-11T15:00Z.

• 309 km/shalf-angle 27°first seen 2026-09-11 14:36 UTC · DONKI record

  CME visible to the NW in SOHO LASCO C2/C3. The CME is obscured by the pylon in GOES CCOR-1 imagery and is not clearly visible in STEREO A COR2. The potential source may be an eruption from AR 14521 (N09W77) in SDO AIA 193 starting around 2026-09-11T11:52Z, best seen as moving field lines.

• 391 km/shalf-angle 16°first seen 2026-09-11 06:24 UTC · DONKI record

  CME visible to the NW in SOHO LASCO C2/C3 and STEREO A COR2. The CME is not visible in GOES CCOR-1 due to Earthshine. The potential source may be near the NW limb as seen from STEREO A EUV 195 imagery. A possible eruption with moving field lines can be seen around 2026-09-11T04:25Z. The CME overlaps in the field of view with the CME first seen in SOHO LASCO C2 at 2026-09-11T05:36Z.

Most coronal mass ejections are not directed at Earth. A speed here describes the ejection, not an impact: whether one reaches Earth, and when, is a separate modelled question that this catalogue does not answer.

Each record names the instrument and energy channel that detected the event, because a detection in one channel is not a detection in another.

Provenance

Every value on these pages is fetched from NOAA SWPC or NASA CCMC and carries the provider's own timestamp. Nothing is simulated, interpolated or filled in: when a provider cannot be reached, the panel says so and shows no number. There is no overall “space weather score” here — the agencies publish scales, and a single figure invented on top of them would be an opinion wearing NOAA's authority.
