Комментарий (на английском языке): Solar activity was at very low levels and is expected to remain so. No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery. The filament eruption that was observed yesterday from the north-east quadrant was analysed and is not expected to impact Earth. The greater than 10 MeV proton flux was at background levels over the past 24 hours. It is expected to stay at background levels for the next 24 hours. The greater than 2 MeV electron flux exceeded the threshold value of 1000 pfu between 12:10 and 22:10 UT Aug 31, as well as reaching the threshold again in the morning of Sep 01. It is expected to continue to be at moderate to high levels during the coming days. The solar wind conditions were enhanced over the period, with the solar wind speed ranging between 530 and 640 km/s. The total magnetic field varied between 3 and 8 nT. Bz had a minimum value of -7 nT. The direction of the interplanetary magnetic field (phi angle) was mostly directed away from the Sun (positive sector). The solar wind conditions are expected to remain enhanced over the next 24 hours due to the continued influence from the high-speed stream from the recurrent coronal hole that crossed central meridian on August 28. Geomagnetic conditions were at quiet to active levels (K Dourbes and NOAA Kp recorded values of 2-4 and 3-4, respectively). Geomagnetic conditions are expected to be mostly unsettled to active during the next 24 hours with a slight possibility of minor geomagnetic storm levels being reached.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 000,
