Сонячно-активні області та спалахи

Solar flaring activity was low over the past 24 hours, with multiple C-class flares recorded. The largest flare was a C2.6 flare (SIDC Flare 7921), peaking at 00:59 UTC on June 10, associated with SIDC Sunspot Group 870 (NOAA Active Region 4465; magnetic type beta- gamma-delta). There are currently eight numbered active regions on the visible solar disk. SIDC Sunspot Group 870, which remains the most complex active region on the solar disk and shows a bipolar region close to the main spot, possibly with an anti-Hale orientation, was the main driver of the flaring activity observed over the past 24 hours, together with SIDC Sunspot Group 892 (NOAA Active Region 4466; magnetic type beta). Low flaring activity was also produced by SIDC Sunspot Group 891 (NOAA Active Region 4464; magnetic type beta) and by the unspotted SIDC Sunspot Group 889 (NOAA Active Region 4461). A new region emerged and was numbered SIDC Sunspot Group 893, currently located near S07E01, but it remained quiet, as did SIDC Sunspot Group 884 (NOAA Active Region 4456; magnetic type beta), which is currently approaching the west limb. The remaining active regions are relatively simple (magnetic type alpha or beta) and did not produce any significant flaring activity. Solar flaring activity is expected to remain low over the next 24 hours, with C-class flares expected and a chance of M-class flares.

Several coronal mass ejections (CMEs) were detected in the available coronagraph imagery over the past 24 hours. A slow CME (SIDC CME 673) was first observed in SOHO/LASCO-C2 from around 16:36 UTC on June 9, directed primarily towards the northeast from Earth's perspective. It was associated with a filament eruption observed from around 15:00 UTC on June 9 in the vicinity of SIDC Sunspot Group 825 (NOAA Active Region 4463), together with coronal dimming. Preliminary analysis suggests that a glancing blow at Earth around June 14 cannot be excluded. Further analysis is ongoing to better estimate the potential impact. Another CME (SIDC CME 674) was first observed in SOHO/LASCO-C2 from around 21:36 UTC on June 9, directed primarily towards the southwest from Earth's perspective. The CME was likely associated with a C2.3 flare (SIDC Flare 7918), peaking at 19:18 UTC on June 9, produced by SIDC Sunspot Group 889 (NOAA Active Region 4461), and with coronal dimming. This CME partially overlaps in coronagraph imagery with a far-sided CME first observed from around 21:12 UTC. Further analysis is ongoing to determine whether this event has an Earth-directed component.

Over the past 24 hours, solar wind parameters (ACE and DSCOVR) reflected the waning influence of an ICME. The solar wind speed decreased from around 480 km/s to 390 km/s. The interplanetary magnetic field remained below 9 nT. Slow solar wind conditions are expected over the next 24 hours, with a chance of a weak enhancement from late on June 11 due to the possible arrival of a high-speed stream from the negative polarity coronal hole SIDC Coronal Hole 147.

Геомагнетизм

Geomagnetic conditions were quiet to unsettled globally (NOAA Kp = 1 to 3). Locally over Belgium, active conditions (K-Bel = 4) were reached between 15:00 and 18:00 UTC on June 9. Mostly quiet to unsettled geomagnetic conditions are expected over the next 24 hours. From late on June 11, active conditions are expected, with a possible isolated minor to moderate storm interval in response to the arrival of the high-speed stream from a negative polarity coronal hole (SIDC Coronal Hole 147).

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10pfu threshold level over the past 24 hours and is expected to remain so over the next 24 hours.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux, as measured by GOES-19, was mostly above the 1000 pfu threshold until 19:50 UTC on June 9 and remained below the threshold for the rest of the period. The greater than 2 MeV electron flux is expected to remain below the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence was at moderate levels and is expected to be at normal to moderate levels over the next 24 hours.
