Bulletin
Solar flaring activity is extremely low, and since there are no active regions observed on the visible side of the solar disc, we do not expect C-class or even B-class flares in the coming hours. During last 24 hours there were no Earth directed CMEs and the solar protons remained at the background level. The Earth is still inside the slow solar wind with the speed of about 340 km/s, and the interplanetary magnetic field magnitude is fluctuating between 2 and 4 nT. Presently geomagnetic conditions are quiet and we expect them to stay so in the coming hours.
