Bulletin
Solar activity remains low, without any flares reported. We expect such a low level of solar flaring activity to continue in the coming hours. During last 24 hours there were no Earth directed CMEs and the solar protons remained at the background level.
Earth is inside the slow solar wind with the speed of about 330 km/s and the interplanetary magnetic field magnitude of 4 nT. The geomagnetic conditions are presently quiet and we expect them to remain so in the coming hours.
