Комментарий (на английском языке): Solar Active Regions and flaring: The solar flaring activity was at low levels, with several C-class flares being detected in the last 24 hours. The largest flare was a C2.2 flare, peaking at 00:07 UTC on June 08, associated with NOAA AR 3327 (beta-gamma-delta class). This region remains the largest and most complex active region on the disk but produced only low C-class flares. Isolated C-class flaring was produced by NOAA AR 3324 and by NOAA AR 3331 (beta class). NOAA AR 3323 (beta-gamma class) is the second most complex active region on the visible solar disc but remained quiet. Other regions on the disc have simple configuration of their photospheric magnetic field (alpha and beta) and did not show any significant flaring activity. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours with a small chance for isolated X-class flare. Coronal mass ejections: In the past 24 hours, several coronal mass ejections (CME) and flows were observed in the available SOHO/LASCO coronagraph imagery and automatically detected by the Cactus tool over. In particular, the CME was observed in SOHO/LASCO-C2 at around 21:27 UTC on June 08. The CME is likely related to the small filament eruption in the southwestern quadrant with an accompanying on disc dimming and a type II radio burst detected around 21:14 UTC on June 08. The CME appears narrow and slow and is unlikely to arrive to Earth. However, a full analysis is still ongoing, and more details will be provided later. No other Earth- directed CMEs have been detected in the available coronagraph imagery. Solar wind: Over the past 24 hours the solar wind parameters (ACE and DSCOVR) indicated a return to a slow solar wind regime. The solar wind speed decreased from values around 345 km/s to 280 km/s. The interplanetary magnetic field magnitude was about 5 nT. The southward component of the interplanetary magnetic field fluctuated between -5 nT and 4 nT. The magnetic field orientation was in the positive sector (field directed away from the Sun). Slow solar wind conditions are expected to prevail on June 09. From June 10, the solar wind from a coronal hole with positive polarity in the northern hemisphere may arrive to the Earth, but since the coronal hole is located at high latitudes, the corresponding high speed stream may miss the Earth. Geomagnetism: The geomagnetic conditions over the past 24 hours were quiet. Mostly quiet geomagnetic conditions are expected, with chances of active levels from June 10 if the high speed stream from the positive polarity coronal hole in the northern hemisphere arrives. Proton flux levels: Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so over the next days. Electron fluxes at GEO: The greater than 2 MeV electron flux was below the 1000 pfu threshold and is expected to remain below this threshold for the next days.The 24h electron fluence was at normal level. The electron fluence is expected to be at normal levels in the next days.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 165,
