太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with only C-class flares. The largest flare was a C4.3 flare (SIDC Flare 8016) peaking on June 25 at 00:22 UTC, which was produced by SIDC Sunspot Group 902 (NOAA Active Region 4478). A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 899 (NOAA Active Region 4475) has the most complex magnetic configuration (Beta-Gamma). SIDC Sunspot Group 899 (NOAA Active Region 4475) and SIDC Sunspot Group 902 (NOAA Active Region 4478) are in charge of the majority of the flaring activity of the past 24 hours. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

日冕物質拋射

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

日冕洞

The northern mid latitude negative polarity SIDC Coronal Hole 142 just finished crossing central meridian.

太陽風

The solar wind parameters became slightly disturbed, following the arrival of the high speed stream. The solar wind speed around 700 km/s and an interplanetary magnetic field of 7nT, and BZ reaching a maximum negative value of -9nT. Similar conditions can be expected for the next 24 hours.

地磁

Geomagnetic conditions active to minor storm levels globally and unsettled to active at local levels (Kp up to 5, K_Dourbes up to 4). Active to minor storm conditions can be expected for the next 24 hours, under the continued influence of high speed stream.

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 remained below the 1000 pfu alert threshold, and is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
