Bulletin

The solar activity was at very low levels over the past 24 hours. No significant solar flares have been observed. Catania sunspot group 28 (NOAA Active Region 2757) has continued to decay. The solar activity is expected to remain at very low levels in the next 24 hours with quiet flaring conditions. No Earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraph imagery. The greater than 10 MeV solar proton flux was at nominal levels and is expected to remain so.

In the past 24 hours the solar wind speed remained slightly enhanced in the range of 350 to 440 km/s. The total magnetic field strength was within 2-7 nT. The Bz component was mostly negative with a minimum value of -5 nT. The interplanetary magnetic field has been predominantly in the negative sector with isolated positive intervals. The solar wind conditions are expected to slowly return to nominal levels over the next 24 hours. Geomagnetic activity has been quiet to unsettled with K Dourbes and NOAA Kp indices in the ranges 1-2 and 1-3, respectively. The geomagnetic conditions are expected to be quiet over the next 24 hours with possible isolated unsettled periods.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 011, na základě 10 stanic.
