Bülletään

Solar activity remains to be low despite the appearance of the new active region NOAA AR 2716, which emerged during last 24 hours and is presently situated close to the center of the solar disc. We expect such a low flaring activity (without C-class flares), to persist in the coming hours. Coronagraph images do not show signatures of the Earth directed CMEs, and the solar protons are at the background level.

Solar wind speed presently amounts about 500 km/s. The maximum solar wind speed (about 580 km/s), during last 24 hours was reached at about 16:00 UT on July 21. The interplanetary magnetic filed magnitude is presently about 4 nT. The fast solar wind, associated with extended equatorial coronal hole which reached central meridian in the early morning of July 21, is expected at the Earth in the mid of the day on July 24. The arrival of the fast flow might induce active geomagnetic conditions late on July 24. The geomagnetic conditions are presently quiet to unsettled and we expect such a geomagnetic conditions to persist in the coming hours.
