Solar Activity
.24 hr Summary...
Solar activity was very low. Region 2886 (S19W15, Hsx/alpha) was quiet and unchanged. Region 2887 (S24E37, Dki/beta) produced multiple B-class flares and exhibited minor development this period. No Earth-directed CMEs were observed.
.Forecast...
Solar activity is expected to be at very low levels over 24-26 Oct, with a chance for C-class activity and a slight chance for R1-R2 (Minor-Moderate) flare activity due to the flare potential from Region 2887.

Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to be at normal to moderate levels over 24-26 Oct and the greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind
.24 hr Summary...
Solar wind parameters were at background levels. Solar wind speed values ranged between 335-385 km/s, total field strength varied between 2-6 nT, and Bz briefly reached -5 nT late in the period.
.Forecast...
Background solar wind conditions are expected to prevail over 24-26 Oct.

Geospace
.24 hr Summary...
The geomagnetic field was quiet.
.Forecast...
