The new region that emerged south of disk center has been numbered as NOAA AR 2778, it has beta magnetic field configuration. It produced four C-class flares today, the largest was a C4.3 peaking at 06:16 UT. More C-class and possible M-class flares can be expected.

A filament erupted close to central meridian (around N30 in latitude) at 22:00 UT on 26 October. There could be a CME with an Earth directed component, but there is a gap in coronagraph data that hinders its identification. More info will be given when/if the data becomes available.

The greater than 10 MeV proton flux was at background levels over the past 24 hours. It is expected to stay at background levels for the next 24 hours. The greater than 2 MeV electrons are above the 10^3 pfu threshold, as the Earth is still under the influence of a High Speed Stream (HSS) from a coronal hole (CH). The electrons are expected to stay at elevated levels in the next 24 h.

The speed of the solar wind varied between 580 and 510 km/s. The Earth is still inside the HSS from a positive polarity coronal hole. Bz was never below -5 nT and B reached 5 nT. Elevated solar wind speeds are expected for the next 24 hours.

The geomagnetic conditions were up to active levels at planetary index (Kp = 4) and unsettled locally (KDourbes = 3). More active conditions can be expected in the next 48 hours, as the Earth is still under the influence of the HSS.
