The solar flaring activity was very low during last 48 hours, with only few low C-class flares reported. All active regions presently observed on the visible side of the Sun have simple configuration of their photospheric magnetic field (alpha and beta). We can therefore expect a low flaring activity to persist in the coming hours. During last 24 hours there were no potentially Earth-directed CMEs detected in the available coronagraph observations.

The greater than 10 MeV proton flux remained at the background levels, and the greater than 2 MeV electron flux was under the 1000 pfu threshold. The 24h electron fluence is at normal level. We do not expect change in these three parameters in the coming 24 hours.

The in situ data show the arrival of the solar wind originating from the small positive polarity coronal hole that has rotated across the central meridian on November 22. The simultaneous increase of the magnetic field magnitude and the solar wind density that started at about 18:00 UT on November 24, was followed by the increase of the solar wind speed and temperature. The solar wind speed is presently 520 km/s and still increasing. The interplanetary magnetic filed magnitude is fluctuating around 10 nT. The solar wind originating from the equatorial, positive polarity coronal hole that crossed the central meridian on November 23rd is expected at Earth on late November 26. During last 24 hours the geomagnetic conditions were quiet to unsettled. The local station at Dourbes reported Kp=3 and NOAA reported planetary index K=3. We expect unsettled geomagnetic conditions to persist in the coming hours, with possible isolated intervals of the active geomagnetic conditions.
