太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with multiple C-class flares recorded. The largest flare was a C4.5 flare (SIDC Flare 7907), peaking at 04:23 UTC on June 9, associated with SIDC Sunspot Group 870 (NOAA Active Region 4465; magnetic type beta- gamma). There are currently eight numbered active regions on the visible solar disk. SIDC Sunspot Group 870 became more magnetically complex, with a newly emerging bipolar magnetic structure close to the main spot, possibly showing anti-Hale orientation. This region was the main driver of the flaring activity observed over the past 24 hours. Low flaring activity was also produced by SIDC Sunspot Group 860 (NOAA Active Region 4455), which rotated behind the west limb, SIDC Sunspot Group 884 (NOAA Active Region 4456; magnetic type beta), and SIDC Sunspot Group 891 (NOAA Active Region 4464; magnetic type beta). A new region emerged and was numbered SIDC Sunspot Group 892, currently located near N06W07, but it remained quiet. 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.

日冕物質拋射

No Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours.

日冕洞

An equatorial negative polarity coronal hole (SIDC Coronal Hole 147) started to cross the central meridian today, on June 9. The associated high-speed stream is expected to begin influencing the near- Earth environment from late on June 11.

太陽風

At the beginning of the period, solar wind parameters reflected a gradual return toward slow solar wind conditions. The solar wind speed decreased from about 480 km/s to 420 km/s, while the interplanetary magnetic field remained below 5 nT. A shock-like structure was detected in the solar wind data (ACE and DSCOVR) at 09:53 UTC on June 9, with the interplanetary magnetic field jumping from about 6 nT to 10 nT, while the solar wind speed increasing from approximately 420 km/s to 470 km/s. The north-south component of the interplanetary magnetic field (Bz) reached a minimum value of -6 nT. This disturbance is possibly related to the late arrival of the ICME associated with the June 6 CME (SIDC CME 672). Solar wind conditions are expected to remain slightly elevated on June 9-10 before gradually returning to slow solar wind conditions, 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.

地磁

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

質子通量水平

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 for the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux, as measured by GOES-19, exceeded the 1000 pfu alert threshold for a short interval over the past 24 hours, reaching a peak value of 1310 pfu. The greater than 2 MeV electron flux may exceed the alert threshold over the next 24 hours. The 24-hour electron fluence was at moderate levels over the past 24 hours and is expected to remain at normal to moderate levels over the next 24 hours.
