Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C7.2 flare (SIDC Flare 7895), peaking at 02:49 UTC on June 08, associated with SIDC Sunspot Group 870 (NOAA Active Region 4465; magnetic type beta). There are currently nine numbered active regions on the visible solar disk. SIDC Sunspot Group 870, which is currently rotating from behind the northeast limb and likely corresponds to returning NOAA Active Region 4411, was the main driver of the flaring activity observed over the past 24 hours, together with SIDC Sunspot Group 890 (NOAA Active Region 4462; magnetic type beta). Low flaring activity was also produced by SIDC Sunspot Group 860 (NOAA Active Region 4455; magnetic type alpha) and SIDC Sunspot Group 886 (NOAA Active Region 4458; magnetic type beta), which are currently approaching the west limb, as well as by SIDC Sunspot Group 887 (NOAA Active Region 4459; magnetic type beta) and SIDC Sunspot Group 891 (NOAA Active Region 4464; magnetic type beta). 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 be at low to moderate levels over the next 24 hours, with C-class flares expected and M-class flares likely.

Vyhazování koronální hmoty

No Earth-directed coronal mass ejections (CMEs) were observed in the available coronagraph imagery over the past 24 hours.

Solární bouře

Over the past 24 hours, solar wind parameters (ACE and DSCOVR) reflected the waning influence of an ICME, probably mixed with high-speed stream influences. The solar wind speed decreased from around 560 km/s to 480 km/s. The interplanetary magnetic field remained weak, below 5 nT. Slow solar wind conditions are expected over the next 24 hours, with a slight enhancement possible from the second half of June 8 in response to the arrival of the ICME associated with the June 6 CME (SIDC CME 672).

Geomagnetismus

Geomagnetic conditions were quiet to unsettled both globally and locally over Belgium (NOAA Kp = 1 to 3-; K-Bel = 1 to 3). Geomagnetic conditions are expected to reach minor storm levels over the next 24 hours, with isolated moderate or major storm periods possible, due to the expected ICME arrival associated with the CME that lifted off the solar surface at around 14:11 UTC on June 6 (SIDC CME 672).

Úrovně protonového toku

Over the past 24 hours, the greater than 10 MeV GOES proton flux was still slightly elevated but remained well below the 10 pfu threshold. The proton flux is expected to remain below the 10 pfu threshold over the next few days. There is a small chance that the proton flux may increase in case of further strong flaring activity.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19, was mostly above the 1000 pfu threshold until 08:35 UTC on June 08, with only short intervals below the threshold. After 08:35 UTC, the electron flux remained below the threshold. The greater than 2 MeV electron flux is expected to remain mostly below the 1000 pfu threshold over the next 24 hours. The electron fluence was at moderate levels and is expected to be at normal to moderate levels over the next 24 hours.
