Bülletään

Catania reports two sunspot groups on the visible side of the solar disc, group 32 (NOAA AR 2662) and group 33 (not numbered by NOAA). Only reported flare in the last 24 hours was B1.9 flare which originated from the Catania sunspot group 33 (peaked at 19:07 UT on June 14). All the observed CMEs, during the last 24 hours, were narrow and will not arrive to the Earth.

The Earth is presently inside the slow solar wind with the speed of about 440 km/s, and the interplanetary magnetic field magnitude is 4 nT. Two large coronal holes, one on the north solar hemisphere and one on the south solar hemisphere, have reached central meridian yesterday evening. The associated fast solar wind is expected to arrive at the Earth early in the morning of June 18. The fast solar wind associated with the large equatorial coronal hole which has reached the central meridian in the morning of June 12, is expected to arrive at the Earth early morning of June 16. The geomagnetic conditions are presently quiet, we expect unsettled to active conditions due to arrival of the fast solar wind starting from June 16.
