Комментарий (на английском языке): Solar activity was low in the past 24 hours. NOAA active region 2808 (Catania groups 78 and 90) produced one B-class flare in the past 24 hours. NOAA region 2809 has lost some of its magnetic complexity and is expected to continue to decay. A new active region has emerged at S28W12 but it is not expected to cause any significant activity in the next 24 hours. Overall, solar activity is expected to remain at low levels. No Earth-directed Coronal Mass Ejections (CMEs) have been observed in coronagraph data. The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux exceeded the 1000 pfu threshold during the past 24 hours and is expected to remain at this level in the next 24 hours. The 24h electron fluence was at moderate levels and it is expected to remain at this level in the next 24 hours. Solar wind speed showed a generally decreasing trend over the period, with values between 460 and 580 km/s. The total interplanetary magnetic field varied between 2 and 6 nT. The magnetic field phi angle was predominantly in the negative sector (magnetic field directed towards the Sun). Solar wind conditions are expected to continue to slowly return to background conditions. Geomagnetic conditions reached active conditions with a period of local minor geomagnetic storming (NOAA Kp 2-4 and local K Dourbes 1-5). Geomagnetic conditions are expected to be at quiet to unsettled levels over the next 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 027,
