太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C6.6 flare (SIDC Flare 8020) peaking on June 25 at 15:03 UTC, which was produced by SIDC Sunspot Group 886 (NOAA Active Region 4478). A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 886 (NOAA Active Region 4478) currently located at S06E59 has a Beta-Gamma-Delta magnetic configuration and was in charge of the majority of the flaring over the past 24 hours. Solar flaring activity is expected to be high over the next 24 hours, with M-class flares very likely and a chance for X-class flares.

日冕物質拋射

No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

太陽風

Earth continues to be under the influence of high speed streams (HSSs) from the successive coronal holes which crossed the central meridian on June 22 till June 25. The solar wind speed ranged between 650 km/s to 700 km/s.The interplanetary magnetic field was around 6nT, with the Bz reaching a minimum value of -6 nT. Similar solar wind conditions are expected in the next 24 hours.

地磁

Geomagnetic conditions were unsettled to active both locally and globally (Kp up to 4, K_Bel up to 4). Similar quiet to unsettled conditions can be expected for the next 24 hours.

質子通量水平

The greater than 10 MeV proton flux, as measured by GOES-18, was below the 10 pfu 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 was mainly below the 1000 pfu alert threshold, with a short and minimal crossing of that threshold on June 25 7:25 UTC as reported by GOES 18. Similar short and minimal crossing of the 1000 pfu threshold by the greater than 2 MeV electron flux is expected during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
