Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was at moderate levels, with multiple C-class flares and four M-class flares recorded in the past 24 hours. The largest flare of the period was an impulsive M9.3 flare, peaking at 13:01 UTC on June 23, associated with NOAA AR 3723. The region corresponds to the return of old NOAA AR 3697, which produced several X-flares in the previous rotations. NOAA AR 3712, that rotated over the west limb, produced two M-class flares (M1.3 and M1.8, peaking at 04:17 UTC and 04:52 on June 24). Low flaring activity was also produced by NOAA AR 3716 (beta class) and NOAA AR 3720 (beta). The solar flaring activity is expected to be at moderate levels over the next 24 hours, with M-class flares possible and a small chance of isolated X-class flares. Coronal mass ejections: A partial halo coronal mass ejection (CME) was observed in LASCO/C2 coronagraph data starting at 03:48 UTC on June 24th. The CME is directed primarily to the southwest from the Earth's perspective and is likely associated with a prominence eruption from behind the southwest limb. Based on the source location, no Earth-directed component of this CME is expected. No other Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours. Solar wind: The solar wind parameters showed a return to the slow solar wind regime. The wind speed decreased form 360 km/s to 300 km/s. The southward component of the interplanetary magnetic field fluctuated between -5 nT and 7 nT, being mainly positive. The total interplanetary magnetic field decreased to values around 3 nT. The magnetic field orientation was predominantly in the negative sector (field directed towards the Sun). Slow solar wind conditions are expected to prevail over the next few days. Geomagnetism: The geomagnetic conditions over the past 24 hours were at quiet to unsettled levels globally (NOAA Kp = 1-3-). Locally, a single active period between 12:00-15:00 UTC on June 23 was observed over Belgium (K-Bel = 1-4). Mostly quiet conditions are expected over the next 24 hours. 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, with possible enhancements in case of increased solar activity over the next few days. Electron fluxes at GEO: The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain below this threshold over the next days. The 24-hour electron fluence was at nominal levels. The electron fluence is expected remain at nominal levels over the next days.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 152,
