Комментарий (на английском языке): Solar activity was at very low levels. NOAA 2782 remained an inactive plage region. A new active region NOAA 2783 rotated from the East limb yesterday. It was classified as Hsx/alpha and did not produce any significant flaring activity in the last 24 hours. The solar activity is expected to remain very low with slight changes for a C class flare. No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery. 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. The greater than 2 MeV electron flux remained under the 1000 pfu threshold and is expected to remain so. The 24h electron fluence was at nominal levels and is expected to remain so for the next 48 hours. Solar wind speed remained very slow with highest value below 330 km/s (ACE and DSCOVR). The total magnetic field was very weak with a maximal strength of 6.2 nT. The Bz component varied between -5.7 nT and +3.7 nT and the interplanetary magnetic field as measured by the phi angle was predominantly in the positive sector, directed away from the Sun. Geomagnetic activity was quiet and is expected to remain so within the next 48 hours. On Nov 20th in the afternoon some influence form a high-speed stream related to the small coronal hole observed yesterday (CH 97) might lead to unsettled or possibly isolated active conditions. Another positive- polarity coronal hole (CH 96) was observed close to the central meridian today. The high-speed stream from it might further induce prolonged active conditions starting from Nov. 21th.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 010,
