Wow! Significant dimming visible across almost the entire disk, a clear signature of a powerful CME. This eruption is truly massive. #SpaceWeather

Filament erupted near disk center in the southern hemisphere. The resulting CME appears mainly SW-directed. Glancing impact might be possible.

G3 (Strong) geomagnetic storm is officially confirmed. Solar wind speed has increased to around 900 km/s now. Further intensification to G4 (Severe) levels is possible.

In Kiruna, Sweden, the aurora is only in the southern part of the sky (a sign of a very strong display!)

G2 geomagnetic storm is in progress. Solar wind speed has now increased to around 800 km/s. If Bz remains strongly southward for an extended period, this storm could potentially intensify to G3-G4 levels.

Here we go! The M6.4 CME looks pretty good here in coronagraph imagery, forming a clear full halo with a strong shock that should have an Earth-directed component.

Another strong eruption from AR4549. The M6.4 flare launched an impressive CME, mainly directed to the NW.

Bz turns strongly southward (−21 nT). G2 warning issued, with G3 conditions possible if this persists.

Strong CME impact, likely associated with the M6.7 flare. Solar wind speed has increased to 600 km/s, with Bt around 45 nT and an impressive density spike near 120 p/cm³. Unfortunately, Bz stays northward. Hopefully, it turns southward in the coming hrs.

AR4549 erupts again! An M6.7 flare produced an impressive coronal wave. The central coronal hole appears to be deflecting the CME mainly northward, though a potential Earth-directed component is still possible.

A gorgeous eruption (accompanying a coronal wave) associated with an M1.4 flare from AR 14549. The CME may be Earth-bound for 9-Oct arrival. Personal note: I have been hospitalized since 15-Sep. I think the most critical phase has passed, and look forward to come back soon.

NASA’s ENLIL model predicts the CME shock will arrive on Oct 9th around 04:00 UTC (+/- 7 hrs) with an estimated speed of 570 km/s.

M1.4 flare produced a full-halo CME. Most of the CME is heading northward, though an Earth-directed component is present.

An M1.4 flare occurred from sunspot AR4549. The event was eruptive and likely launched an Earth-directed CME.

Tonight’s aurora has a purple hue. The KP is ~4. We are approaching high beta so there is more light creeping over the horizon. It mixes the colors and you can see the satellites in the nights sky. (14mm, 1/4 interval, broken into two parts)

Another large eruption from behind the eastern limb produced a nice CME.

What a spectacular mess of incoming (more or less) CMEs in the SWPC WSA-ENLIL model prediction. 500 km/s? If Bz cooperates we should see some decent activity. Although it could be quite messy ...

Another incoming CME! This one was launched today after an eruptive C5.0 flare in AR 4524. The CME is moderately fast at 1085 km/s. The arrival is expected on September 8th around 19h UTC (+/- 7hrs). The Earth-bound traffic is getting busy.

An impressive coronal wave from a major eruption associated with an M1.0 flare in AR 14520. An S1 storm (>10 MeV protons of 17.8 pfu) was observed.

Check out how fast the radiation storm rose, especially the higher energies (100 MeV). They reached the S1-level easily 30 minutes before the low energies did. Now that is a hard spectrum! This means the blast wave created by the eruption was extremely strong and fast, despite the flare being weak (only an M1-flare). This is why we cannot judge the strength of radiation storms or solar storm launches by the intensity of a solar flare!
