Комментарий (на английском языке): The solar activity was mostly quiet over the past 24 hours. Tow regions are visible in the solar disc seen from Earth (NOAA-AR 2780, and NOAA-AR 2781). NOAA-AR 2780 has decayed, while the second region (NOAA-AR 278) has produced few C1.1-class flare. The solar activity is expected to remain mostly at low levels with a probability of small C-class flare. No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery in the last 24 hours. The all quiet alert has, however, been switched off, as the recent emerge region shows some activity that may include in the future Earth-directed coronal mass ejections. 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 electrons flux was below the 10^3 pfu threshold over the past 24 hours. It is expected to remain at low for the next 24 hours as the solar wind parameters are close to nominal levels and then may slightly increase to moderate levels slightly above 10^3 pfu threshold. The Earth is currently under the influence of the slow solar wind streams. The solar wind parameters (DSCOVR) showed nominal values with the solar wind speed was below 400 km/s, the total interplanetary magnetic field below 5 nT, and the Bz magnetic field components fluctuating between -3.3 nT and 3 nT. The solar wind parameters may slightly be enhanced later on November 5 due to the influence of the solar wind coming from the south coronal hole that extends up to -30 degree latitude. Geomagnetic conditions were quiet. Quiet conditions are expected for the next day, then unsettled conditions are expected with the arrival of the enhanced solar wind conditions later on November 5.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 020,
