Bulletin

There are no numbered active regions on the visible side of the Sun and solar activity is extremely low, without reported flares. The new active region is rotating from behind of the East solar limb, presently only partially on the visible side of the Sun. We expect a low level of flaring activity to persist in the coming hours. No Earth directed CMEs have been observed and the solar protons remained at background level in the past 24 hours.

The solar wind speed has decreased to value of about 300 km/s and the interplanetary magnetic field magnitude is about 2nT. The geomagnetic conditions are quiet and we expect it will remain so in the coming hours. The arrival of the fast solar wind, from the extended equatorial coronal hole which crossed central meridian yesterday, is expected on the midday of May 15 and it might induce active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 000, based on 15 stations.
