Комментарий (на английском языке): Solar activity over the past 24 hours was at low levels with only four low C-class flares. The largest recorded activity was a C2.7-class flare (peak time 21:13 UT) from a dipole active region NOAA 2982 (beta) in the vicinity of the central meridian. Two C-class flares were produced from the behind the west limb, from previous active regions NOAA 2975 and NOAA 2984. The remaining flaring activity was produced by NOAA 2978 (beta), which is currently the largest active region with largest number of sunspots on the visible solar disk. The X-ray flare activity is expected to be at low levels for the next 24 hours with low chances for M-class flaring. Two notable CME events were recorded in the available coronagraph imagery related to behind the limb activity in the south-west quadrant and to a prominence eruption at the north-east limb. None of those is expected to have an Earth-directed component. A long filament erupted in the south-east quadrant in the vicinity of NOAA 2982 and was related to the C2.7 class flaring activity. The resulting CME would probably miss the Earth. The full halo CME detected by LASCO C2 coronagraph data on April 3rd is expected to arrive at Earth in the morning of April 6th. The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours, though some enhancements are possible related to the expected ICME arrival. The greater than 2 MeV electron flux was oscillating around the 1000 pfu threshold is expected to continue to do so within the next 24 hours. The 24h electron fluence was at moderate levels over the past 24 hours and is expected to return to be at the border of moderate to nominal levels in the next 24 hours. Over the past 24 hours the solar wind parameters (ACE and DSCOVR) were under the waning of influence of the high speed stream. The solar wind velocity was gradually decreased towards 400 km/s. The interplanetary magnetic field had a maximum value of 7.8 nT with a minimum Bz of -4.5 nT. The B field remained predominantly in the negative sector (directed towards the Sun). The solar wind parameters are expected to slowly return towards background slow solar wind conditions today and get enhanced tomorrow with expected ICME arrival. The geomagnetic conditions over the past 24 hours were globally quiet and registered a single unsettled period locally in Belgium. Mostly quiet to unsettled geomagnetic conditions are expected until the end of the day and unsettled to active conditions with minor storm levels are expected for tomorrow and throughout April 7th.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 073,
