Over the past 24 hours solar activity has been low. No significant flares have been recorded. Catania group 56 (NOAA AR region 2682) increased its magnetic complexity and produced two B class flares peaking at 13:31 and 14:32 UT yesterday (29-Sep-2017). No Earth directed Coronal Mass Ejections (CMEs) have been detected in coronograph observations. Integral proton flux for protons with energies above 10 MeV remained at background level over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with some probability of C-class flares. The Earth remains under influence of the fast solar wind stream. The solar wind speed is slowly decreasing from 640 km/s till 510 km/s over the past 24 hours. The interplanetary magnetic field magnitude remained between 4 and 5 nT, and the Bz component fluctuating between -4.5 and 4.5 nT being mainly negative. Disturbed geomagnetic conditions were observed with Kp-NOAA up to 4 (K-Dourbes up to 3) due to the fast solar wind and the southward Bz component of the interplanetary magnetic field over several consecutive intervals. The geomagnetic conditions are expected to vary between unsettled to active conditions today, in particular, if the Bz component stays negative for longer periods. Tomorrow (1-Oct-2017) we expect quiet to unsettled geomagnetic conditions as the high speed stream will decrease.
