|---|---|---|---|---|---|---|---|---|
| Coronal mass ejection — 2026-10-02 19:48 UTC | Coronal mass ejection | — | 595 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | Faint narrow CME with an anvil-like front seen to the NE in SOHO LASCO C2/C3 and GOES CCOR-1 and fully covered by a large data gap in STEREO A COR2. Its source is likely the notable prominence off/behind the east limb that is best seen in SDO AIA 304/171 and GOES SUVI 304/284. In SUVI it this filament is seen deflecting northwardly. | |
| Coronal mass ejection — 2026-10-02 23:36 UTC | Coronal mass ejection | — | 654 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | This CME is visible to the east in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. The source is likely far-sided as there are no source signatures on the Earth-facing disk around the time of this event. | |
| Coronal mass ejection — 2026-10-03 21:24 UTC | Coronal mass ejection | — | 273 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | Extremely faint CME/outflow with an unclear front seen to the NE in SOHO LASCO C2 and in early C3 and GOES CCOR-1 difference imagery and covered by a data gap in STEREO A COR2. It is not seen in white light coronagraph imagery. No clear source was found in EUV imagery for this outflow. | |
| Coronal mass ejection — 2026-10-04 17:00 UTC | Coronal mass ejection | — | 289 km/s | 1 | — | SOHO: LASCO/C2 | Filament eruption observed to the SE in SOHO LASCO C2. In real-time the event is slow and not yet observed in other coronagraphs, but will likely be partially obscured by the LASCO C3 and GOES CCOR-1 pylons. The source is a far-sided filament eruption over the SE limb observed in SDO AIA 171/193/304, and GOES SUVI 304, starting around 2026-10-04T15:30Z as filament ejecta and field line movement. It is unclear how far-sided the source is, but being near the limb it is likely within E90-E120. | |
| Coronal mass ejection — 2026-10-05 07:48 UTC | Coronal mass ejection | — | 701 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | Wide CME observed to the NE in SOHO LASCO C2/C3 and GOES CCOR-1, and to the NW in STEREO A COR2. The source is a far-sided filament eruption over the NE limb, observed in SDO AIA 171/193/304 as field line movement, EUV wave, and filament ejecta starting around 2026-10-05T07:18Z, although these features are better observed in the wider field-of-view in GOES SUVI 171/193/284/304. Also observed weakly in STEREO A EUVI over its NW limb starting in EUVI 304 as filament ejecta around 2026-10-05T06:45Z and in EUVI 195 as field line movement around 2026-10-05T07:25Z. | |
| Coronal mass ejection — 2026-10-05 21:12 UTC | Coronal mass ejection | — | 266 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | This CME is visible to the northwest in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is likely related to a far-sided filament eruption which begins to lift-off around 2026-10-05T19:00Z as seen in SDO AIA 131/171/193/304 and GOES SUVI 131/171/195/284/304 imagery. | |
| Coronal mass ejection — 2026-10-08 16:12 UTC | Coronal mass ejection | — | 449 km/s | 1 | — | SOHO: LASCO/C2 | CME faintly seen to the east in SOHO LASCO C2/C3 and GOES CCOR-1. The CME may potentially be visible to the west in STEREO A COR2. The potential source for this CME may be beyond the east limb, as moving field lines are seen in SDO AIA 193 starting around 2026-10-08T09:21Z. Some ejecta of material can also be seen beyond the east limb in GOES SUVI 304 as well. | |
| Coronal mass ejection — 2026-10-09 00:45 UTC | Coronal mass ejection | — | 293 km/s | 1 | — | GOES: CCOR-1 | CME 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 08:00 UTC | Coronal mass ejection | — | 270 km/s | 1 | — | GOES: CCOR-1 | CME 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. | |
| Coronal mass ejection — 2026-10-10 12:23 UTC | Coronal mass ejection | — | 763 km/s | 1 | — | STEREO A: SECCHI/COR2, SOHO: LASCO/C2 | Very minor faint and narrow CME seen to the NE in STEREO A COR2 coronagraph in early timestamps. Possibly it is the same faint narrow CME that is also seen at the time NE in SOHO LASCO C2 for a few early timestamps and not seen in C3 or GOES C3. No source has been found in EUV imagery for this event. | |
| Coronal mass ejection — 2026-10-10 22:00 UTC | Coronal mass ejection | — | 351 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | Minor faint, narrow CME/outflow seen to the west in SOHO LASCO C2/C3 and GOES CCOR-1 and covered by the data gap in STEREO A. No clear source has been found for this CME. | |
| Coronal mass ejection — 2026-10-11 09:12 UTC | Coronal mass ejection | — | 374 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | Outflow first seen to the NW in SOHO LASCO C2 starting around 2026-10-11T09:12Z. This feature is much easier to see later in its propagation into SOHO LASCO C3, GOES CCOR-1, and STEREO A COR2. The source is most likely outflow following CME: 2026-10-10T16:15Z but may be related to field line movement seen near the NW limb in SDO AIA 193 starting as early as 2026-10-11T05:00Z. | |
| Coronal mass ejection — 2026-10-12 10:09 UTC | Coronal mass ejection | — | 351 km/s | 1 | — | STEREO A: SECCHI/COR2, SOHO: LASCO/C2 | This CME is visible to the west in SOHO LASCO C2 and STEREO A COR2 imagery. The source is likely far-sided as there are no source signatures visible on the Earth or STEREO A-facing disk. | |
| Coronal mass ejection — 2026-10-12 12:23 UTC | Coronal mass ejection | — | 335 km/s | 1 | — | STEREO A: SECCHI/COR2 | This CME is visible to the west in STEREO A COR2, SOHO LASCO C2/C3, and GOES CCOR-1 imagery. The source is likely related to a filament eruption visible beyond the western limb in STEREO A EUVI 195/304 imagery which lifts-off around 2026-10-12T10:15Z. | |
| Coronal mass ejection — 2026-10-12 19:36 UTC | Coronal mass ejection | — | 365 km/s | 1 | — | SOHO: LASCO/C2, GOES: CCOR-1 | Narrow CME first seen to the SW by SOHO LASCO C2 beginning at 2026-10-12T19:36Z, as well as by GOES CCOR-1 in later frames. This CME is not visible in STEREO A COR2 due to a data gap which began at 2026-10-12T18:58Z. The source of this event is rising field line loops seen originating from beyond the SW limb in SDO AIA 171 beginning at approx. 2026-10-12T18:18Z. | |
| Coronal mass ejection — 2026-10-14 22:09 UTC | Coronal mass ejection | — | 339 km/s | 1 | — | STEREO A: SECCHI/COR2 | CME seen to the West in STEREO A COR2 beginning at 2026-10-14T22:09Z following the end of a data gap. This CME is not seen in SOHO LASCO C2/C3 or GOES CCOR-1 as it is likely obscured by the occulting disk. The source of this CME may be related to an unstable filament seen along the West limb in STEREO A EUVI 304 imagery beginning at approx. 2026-10-14T18:45Z. | |
| Coronal mass ejection — 2026-10-14 23:12 UTC | Coronal mass ejection | — | 360 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME first seen to the NE by SOHO LASCO C2 beginning at 2026-10-14T23:12Z. The source of this event is a large filament eruption seen originating from beyond the NE limb in GOES SUVI 304 imagery beginning at approx. 2026-10-14T21:52Z. Field line opening is also seen in GOES SUVI 284 in association with this eruption. | |
