| Coronal mass ejection — 2026-10-07 13:53 UTC | Coronal mass ejection | — | 310 km/s | 1 | — | STEREO A: SECCHI/COR2, SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | CME first seen to the NE in STEREO A COR2 starting at 2026-10-07T13:53Z. So far it is only visible in COR2A. The source of this CME is a C7.9 class flare from AR 14549 (N10W04) peaking at 2026-10-07T13:17Z best seen in SDO AIA 171. Some dimming and an EUVI wave associated with the eruption can be seen in SDO AIA 193. Some deflection is evident in the measurement of this CME, likely due to it close proximity to a coronal hole to the SE of AR 14549. | |

| Coronal mass ejection — 2026-09-27 06:36 UTC | Coronal mass ejection | — | 399 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME first seen to the West by SOHO LASCO C2 beginning at 2026-09-27T06:36Z, as well as by SOHO LASCO C3, STEREO A COR2 and GOES CCOR-1 in later frames. The source of this event is a small eruption from the vicinity of AR 14534 (N10W95) beginning at approx. 2026-09-27T04:30Z in STEREO A EUVI 195. This CME is likely deflected to the West by a large coronal hole in the vicinity of the eruption. | |
| Coronal mass ejection — 2026-09-30 03:12 UTC | Coronal mass ejection | — | 488 km/s | 1 | 2026-09-30T02:30:00-FLR-001, 2026-10-03T01:26:00-IPS-001 | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME first seen to the West by SOHO LASCO C2 beginning at 2026-09-30T03:12Z, as well as by SOHO LASCO C3, STEREO A COR2 and GOES CCOR-1. The source of this event is a C8.6 flare from Active Region 14535 (N11W48) seen peaking at 2026-09-30T02:46Z. This flare can be seen clearly in SDO AIA 131, along with field line opening, dimming and an EUV wave seen in SDO AIA 171/193/211, GOES SUVI 284 and STEREO A EUVI 195. | |

| Coronal mass ejection — 2026-10-02 08:24 UTC | Coronal mass ejection | — | 270 km/s | 1 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME visible to the NW in SOHO LASCO C2/C3 and GOES CCOR-1. The CME overlaps in the field of view with the CME first seen in STEREO A COR2 at 2026-10-02T00:53Z. The CME may potentially be faintly seen to the NNE in STEREO A COR2. The potential source may be AR 14535, located around N11W75, with a small region of brightening and moving field lines best seen in SDO AIA 193 imagery starting at 2026-10-02T05:52Z. | |
| Coronal mass ejection — 2026-10-01 03:12 UTC | Coronal mass ejection | — | 432 km/s | 2 | — | SOHO: LASCO/C2, SOHO: LASCO/C3, STEREO A: SECCHI/COR2, GOES: CCOR-1 | Faint CME observed to the NW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source is far-sided, approximately ~N12W120, as observed in STEREO A EUVI 195/304 as brightening starting around 2026-10-01T02:35Z. Also observed in SDO AIA 171/193/304 as filament ejecta and field line movement beyond the NW limb starting around 2026-10-01T02:36Z. | |
| Coronal mass ejection — 2026-10-08 16:53 UTC | Coronal mass ejection | — | 504 km/s | 3 | 2026-10-08T15:29:00-FLR-001, 2026-10-10T14:33:00-IPS-001, 2026-10-10T14:35:00-RBE-001 | STEREO A: SECCHI/COR2, GOES: CCOR-1 | CME visible to the NE in STEREO A COR2 and the NW in GOES CCOR-1. There was a real-time data gap in SOHO LASCO imagery at the start of the CME, but this backfilled with additional imagery. The source for this CME is an M6.7 class flare from AR 14549 (N12W20) which peaked at 2026-10-08T15:48Z. The flare is best seen in SDO AIA 131. The accompanying EUV wave which spans the entire NW quadrant of the Earth-facing disk is best seen in SDO AIA 193. The eruption is also visible in STEREO A EUV 195/304 imagery. | |
| Solar flare — 2026-10-08 15:29 UTC (M6.7) | Solar flare | M6.7 | — | — | 2026-10-08T16:53:00-CME-001 | GOES-P: EXIS 1.0-8.0 | — | |
| Coronal mass ejection — 2026-09-19 18:48 UTC | Coronal mass ejection | — | 321 km/s | 1 | 2026-09-19T17:57:00-FLR-001 | SOHO: LASCO/C2 | Faint, minor CME with an unclear front seen to the E-NE in SOHO LASCO C2. Not seen in other coronagraphs. Its source is the long duration C3.3 class flare from unnumbered AR rotating onto disk (N14E90) peaking at 2026-09-19T18:17Z. There is also an associated opening of field lines on/behind the E limb seen in SDO AIA 193 and a minor prominence/ejecta seen in SDO AIA 304/171 starting after 2026-09-19T18:10Z. The initial front is followed by a series of outflows. | |
| Solar flare — 2026-09-19 17:57 UTC (C3.3) | Solar flare | C3.3 | — | — | 2026-09-19T18:48:00-CME-001 | GOES-P: EXIS 1.0-8.0 | The flare was produce by the unnumbered Active Region just behind the limb. This is likely the Active Region that would be numbered AR 14535. | |
| 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 07:15 UTC | Coronal mass ejection | — | 391 km/s | 1 | — | GOES: CCOR-1 | CME 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. | |
| Solar flare — 2026-10-09 13:55 UTC (M1.3) | Solar flare | M1.3 | — | — | 2026-10-09T14:36:00-CME-001 | GOES-P: EXIS 1.0-8.0 | Region 14547 decayed to a plage on 2026-10-08 and rotated off of the Earth-facing disk early on 2026-10-09. This flare may be occulted due to its location near the west limb. | |
| 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 | — | 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. | |

The source of this event is a very large filament eruption seen stretching from approx. S10W50 to N45W50 (centered at approx. N27W50) with liftoff beginning at approx. 2026-09-28T13:51Z as seen in SDO AIA, STEREO A EUVI and GOES SUVI 304. Post eruptive arcades, dimming and wide field line opening can be seen in SDO AIA 171/193/211, GOES SUVI 284 and STEREO A EUVI 195. | |
| Coronal mass ejection — 2026-10-02 00:53 UTC | Coronal mass ejection | — | 255 km/s | 1 | — | STEREO A: SECCHI/COR2, SOHO: LASCO/C2, SOHO: LASCO/C3, GOES: CCOR-1 | CME faintly visible to the NE in STEREO A COR2 and the NW in SOHO LASCO C2/C3 and GOES CCOR-1. The source is likely a gradual eruption with moving field lines best seen in SDO AIA 193 starting around 2026-10-01T17:43Z. Post-eruption arcades are also visible, and best seen after a data gap in STEREO A EUV 195 imagery. The data gap is from 2026-10-01T14:35Z to 2026-10-02T00:55Z. | |
