Bulletin

Solar activity is still very low and there were no flares reported during last 24 hours. We expect such a low level of flaring activity to persist in the coming hours. During last 24 hours we observed few faint and rather narrow coronal mass ejections (CMEs) that, based on the presently available observations, do not seem to be earth-directed. The solar protons remained at the background level.

Earth is presently within the slow solar wind with speed of about 370 km/s and the interplanetary magnetic field magnitude is 2 nT. The solar wind originating from the narrow and extended equatorial coronal hole of negative polarity that reached central meridian in the evening of December 10, might arrive to the Earth late on December 14. The geomagnetic conditions are quiet and we expect them to stay so in the coming hours.
