|---|---|---|---|---|---|---|---|---|
| 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 07:24 UTC | Coronal mass ejection | — | 336 km/s | 1 | 2026-10-04T06:13:00-FLR-001 | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | Faint CME observed to the SW in SOHO LASCO C2, poorly observed in LASCO C3 and GOES CCOR-1, and not in STEREO A COR2; mostly overlapped with following CME: 2026-10-04T07:36Z. The source is likely the first of two paired B-class flares and respective field line movement from AR 14546; this front associated with the B3.2 class flare peaking at 2026-10-04T06:19Z and field line movement in SDO AIA 171. | |
| Coronal mass ejection — 2026-10-04 07:36 UTC | Coronal mass ejection | — | 313 km/s | 1 | 2026-10-04T06:21:00-FLR-001 | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | Faint CME observed to the SW in SOHO LASCO C2, poorly observed in LASCO C3 and GOES CCOR-1, and not in STEREO A COR2; mostly overlapped with preceeding CME: 2026-10-04T07:24Z. The source is likely the second of two paired B-class flares and respective field line movement from AR 14546; this front associated with the B9.3 class flare peaking at 2026-10-04T06:30Z and broad field line movement/dimming in SDO AIA 171/193. | |
| 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 01:26 UTC | Coronal mass ejection | — | 340 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | Faint CME observed to the W in SOHO LASCO C2/C3 and GOES CCOR-1, not observed in STEREO A COR2. The source is AR 14546 starting around 2026-10-05T00:33Z, with brightening and field line movement in SDO AIA 171/193, and some dimming in SDO AIA 193, centered around S21W71. | |
| 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 11:24 UTC | Coronal mass ejection | — | 629 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | Faint CME observed to the SE in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is in the vicinity of AR 14548 (S11E46), as a weak eruption centered around S17E60 starting around 2026-10-05T08:55Z observed in SDO AIA 171/193 as filament brightening and field line movement without the small filament seen cleanly lifting off the disk. | |
| 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 — 2026-10-06 00:00 UTC | Coronal mass ejection | — | 325 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | This CME is visible to the west/southwest in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. This event is not seen in STEREO A COR2 imagery likely due to a data gap from 2026-10-05T14:38Z to 2026-10-06T01:23Z. The source is a small eruption visible from Active Region 14546 (S19W88) as seen in SDO AIA 131/171/193/304 and GOES SUVI 131/171/195/284/304 imagery starting around 2026-10-05T23:15Z. A subsequent opening of field lines visible over the southwest limb in SDO AIA 171/193 and GOES SUVI 171/195/284 imagery at this time as well. | |
| 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 — 2026-10-08 16:24 UTC | Coronal mass ejection | — | 579 km/s | 1 | 2026-10-10T01:48:00-IPS-001, 2026-10-10T14:33:00-IPS-001, 2026-10-10T14:35:00-RBE-001 | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME visible to the west in SOHO LASCO C2/C3 and GOES CCOR-1 as well as possibly faintly to the east in STEREO A COR2. This CME overlaps in the field of view with the CME first seen in STEREO A COR2 at 2026-10-08T16:53Z. The potential source is a filament eruption centered around N05W25 as best seen in SDO AIA 193/304 imagery. The eruption is best seen as dimming starting at 2026-10-08T09:21Z in SDO AIA 193. The filament liftoff can be best seen from the point of view of STEREO A EUV 195/304, in the NE quadrant from the point of view of STEREO A. | |
| Coronal mass ejection — 2026-10-08 20:12 UTC | Coronal mass ejection | — | 453 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | CME visible to the NW in SOHO LASCO C2/C3 and GOES CCOR-1, directly following CME: 2026-10-08T16:53Z in the field of view. The CME is not visible in STEREO A COR2, and a data gap starts at 2026-10-08T18:53Z. The potential source is unclear, with several potential source candidates on the disk. The most likely candidate is a possible eruption from AR 14547 (N15W85) seen starting around 2026-10-08T16:19Z as dimming and moving field lines. The eruption is also faintly visible from the point of view of STEREO A EUV 195 imagery. Another candidate source is a filament eruption starting around 2026-10-08T18:09Z centered around S15E10 as seen in SDO AIA 193/304, but this is not a likely source candidate due to the location of the eruption. This eruption's proximity to a coronal hole may result in some deflection of the eruption. The third possible eruption candidate is activity from AR 14549 (N10W25), but it is not clear if this is a separate eruption from the one that produced CME: 2026-10-08T16:53Z. | |
| Coronal mass ejection — 2026-10-09 14:36 UTC | Coronal mass ejection | — | 315 km/s | 1 | 2026-10-09T13:55:00-FLR-001 | SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | Faint CME with a loop front seen to the NW in the early SOHO LASCO C2 imagery, also seen faintly in C3 and GOES CCOR-1. It is fully covered by long data gap in STEREO A COR2 coronagraph. The source is the occulted (or on-limb) M1.3 flare likely from Active Region 14547 (N15W94), now decayed to a plage, which had just rotated off the visible disk before the flare. Other coronal signatures include a small ejecta seen in SDO AIA 304 at the time of the flare and movement/opening of field lines seen to the NW behind the limb in SDO AIA 171/193 and GOES SUVI 304/284. | |
| Coronal mass ejection — 2026-10-10 08:36 UTC | Coronal mass ejection | — | 368 km/s | 1 | 2026-10-14T03:52:00-IPS-001 | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME observed to the NW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is former AR 14547 (~N15W105) as directly observed by STEREO A around the west limb from SDO. Observed across SDO AIA 131/171/193/211/304 as field line movement and EUV wave, and brightening, starting around 2026-10-10T07:51Z, partially obscured by a rare transit of the moon across the SDO AIA field-of-view. Also seen in STEREO A EUVI 195/304 as brightening, dimming, and field line movement starting around 2026-10-10T07:55Z. | |
| 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 — 2026-10-11 23:12 UTC | Coronal mass ejection | — | 618 km/s | 1 | 2026-10-14T17:28:00-IPS-001 | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | This CME is visible to the east in GOES CCOR-1 and SOHO LASCO C2/C3 imagery. This event is seen in STEREO A COR2, directed towards the east, after it has exceeded the field of view due to a data gap from 2026-10-11T17:38Z to 2026-10-12T01:53Z. The source is a filament eruption spanning S30E30 to S10E05 which begins to lift off around 2026-10-11T22:30Z as seen in SDO 131/171/193/304 and GOES SUVI 131/171/195/284/304 imagery. Dimming is visible in SDO AIA 193 and GOES SUVI 195 imagery, with post eruptive arcades visible starting around 2026-10-11T23:40Z. | |
| 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. |
