Bulletin

The only active region presently observed on the visible side of the Sun is not numbered region on the northern solar hemisphere, approaching to the West solar limb. Another active region (on the Southern hemisphere) is rotating to the visible side of the solar disk. During last 24 hours there was no C-class or even B-class flares reported and we expect such a low level of 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.

The solar wind speed is still low, with present value of about 320 km/s. The interplanetary magnetic field magnitude is 3 nT. The geomagnetic conditions are quiet to unsettled and we expect such a quiet conditions to persist in the coming hours.

Today's estimated international sunspot number (ISN): 000, based on 30 stations.
