Комментарий (на английском языке): Solar Active Regions and flaring: The solar flaring activity was at low levels. The largest flare was a C5.2 flare, peaking at 06:58 UTC on June 12, associated with NOAA AR 3330 and also associated with Type II radio emission. NOAA AR 3327 decayed slightly, while NOAA AR 3231 became more complex. The other regions on the disk are magnetically simple and produced only low-level C-class flares. A new sunspot group began to emerge in the southeastern quadrant, but this is small and as yet unnumbered. The solar flaring activity is expected to be at low levels over the next 24 hours with C-class flares likely and M-class flares possible. Coronal mass ejections: In the last 24 hours there were no Earth-directed Coronal Mass Ejections (CMEs) detected in the available coronagraph observations. Coronal holes: A small negative polarity equatorial coronal hole began to transit the central meridian on June 12. Solar wind: The solar wind conditions continued to reflect the ongoing influence of a weak high-speed stream (HSS). The solar wind speed increased from 400 to 480 km/s. The total interplanetary magnetic field decreased from 12 to 6 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). The solar wind conditions are expected to remain elevated for the next days with the ongoing HSS influence and a there is a low probability for further minor enhancements from late on June 13, due to the possible arrival of the CME from June 09, which was predicted to have a glancing blow at Earth. Geomagnetism: During last 24 hours the geomagnetic conditions were at quiet to unsettled levels (NOAA KP 1-3 and K-Bel 1-3). Geomagnetic conditions are expected to be at quiet to unsettled levels on June 12, increasing to active levels with a chance for isolated minor storm periods from late on June 13, due to the combination of the current high-speed stream influence and a possible glancing blow of the ICME. 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 levels. The electron fluence is expected to be at normal levels in the next days.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 118,
