G1 (Minor) to G2 (Moderate) geomagnetic storms are likely on 09 Oct with the arrival of a CME that was associated with a M1.4 flare from Active Region 4549 on 06 Oct. A high chance for additional M-class flare activity from Region 4549 will persist in the coming days.

Learn about filament eruptions and CMEs by watching this latest SWPC Video posted 30 Sep 2026. A filament eruption occurred on 28 Sep and could bring G1 conditions upon arrival Thursday evening (1 Oct EDT) due a CME flanking edge - glancing blow. @NWS

The solar wind and GOES data issues were resolved. Information is updating on our webpage again.

[NOAA Space Weather Prediction Center @NWSSWPC]

Real Time Solar Wind (RTSW) and some GOES-18/19 observations are unavailable. Troubleshooting is in progress and some GOES-19 data appears to have returned; however, GOES-18 is still unavailable, and the RTSW sources are still out at this time.
