Комментарий (на английском языке): Solar X-ray flux has been below background (B) level throughout the period. There are no spotted regions on disc and X-ray flux is expected to remain at or below background (B) values. There were no Earth directed coronal mass ejections observed in coronagraph data. 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 was at nominal levels over the past 24 hours and is expected to remain so over the next 24 hours. Solar wind conditions were slightly elevated. Solar wind speed reached a maximum of 415 km/s and remained at around 400 km/s during the remainder of the period. The magnetic field strength was enhanced at the start of the period but soon decreased to below 5nT and remained at that level. The magnetic field phi angle was mainly in the towards sector. Solar wind conditions may become more significantly enhanced over the next 48 hours due the possible influence of a high speed stream from the extension of the Northern (positive polarity) polar coronal hole. It remains to be seen to what extent this will set through. Geomagnetic conditions were quiet to unsettled (both NOAA Kp and local K Dourbes 0-3). Geomagnetic conditions are expected to be mostly quiet to unsettled, with some isolated active periods not excluded depending on the strength of the expected Solar wind enhancements.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 000,
