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 C5.7 flare (SIDC Flare 8024) peaking on June 26 at 12:48 UTC, which was produced by SIDC Sunspot Group 886 (NOAA Active Region 4478). A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. Currently the most complex active regions are SIDC Sunspot Group 886 (NOAA Active Region 4478) with a Beta-Gamma-Delta magnetic configuration and SIDC Sunspot Group 899 (NOAA Active Region 4475) with a Beta-Gamma magnetic configuration. These regions were in charge of the majority of the flaring activity of the past 24 hours. Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares very likely and a small chance for X-class flares.

日冕物質拋射

The CME that was first seen in LASCO C2 from 21:15 UTC June 26 is directed towards the south will be further analysed when more data become available in order to assess for any Earth-directed component. No other Earth-directed CMEs have been observed in available imagery.

太陽風

Solar wind conditions are transitioning to slow solar wind conditions after the passage of the High Speed Stream. The solar wind speed decreased from 650 to 550 km/s, the magnetic field decreased from 5nT to 3 nT, and the Bz reached a minimum value of -3 nT. Solar wind conditions are expected to continue the transition to slow solar wind conditions in the next 24 hours.

地磁

Geomagnetic conditions were quiet to unsettled both locally and globally (Kp up to 3, K_Bel up to 3). 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 is above the 1000 pfu alert threshold since June 26 14:30 UTC, and is expected to remain above the threshold during the next 24 hours. The 24h electron fluence has increased to moderate levels and is expected to remain so for the next 24 hours.
