NOAA 2603 produced the strongest event of the period, a B1.9 peaking at 20:42UT. This region has now a mature but small trailing spot, and seems to have simplified magnetically. A strong coronal mass ejection (CME) over the northeast solar limb was observed in LASCO/C2 starting 25 October around 19:00UT. Its source was located on the farside of the Sun (old active region NOAA 2599). No earth-directed CMEs were observed.

Quiet flaring conditions are expected to continue, with a small chance on an isolated C-class flare.

Earth was under the influence of the high speed stream (HSS) from the huge coronal hole (CH). Maximum solar wind speeds near 830 km/s were recorded around 23UT on 25 October (DSCOVR), its current values now fluctuating between 670 and 750 km/s. Bz varied between -15 and +9 nT during the first half of the period, but is currently fluctuating between -6 and +6 nT. The interplanetary magnetic field (IMF) was directed away from the Sun (positive). Kp ranged from active to major geomagnetic storming, while K Dourbes ranged from quiet conditions to moderate storming.

Wind speeds are expected to remain above 500 km/s for the next two days, with periods of sustained negative Bz possible. Hence, mostly unsettled to moderate storm conditions are expected, with a small chance on another major storming interval (K-index = 7).
