太陽活動區和耀斑

Solar flaring activity was very low over the past 24 hours, with only 2 C-class flares. The strongest flare was a C1.2 flare with peak time 08:10 UTC on June 23 2026. A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 898 (NOAA Active Region 4474) currently located at N03W75 has a Beta-Gamma magnetic configuration and was the most complex active region of the last 24 hours. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares likely and a small 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 mid latitude negative polarity coronal hole SIDC CH 149 that first reached the central meridian on June 22 has finished crossing central meridian. The equatorial negative polarity SIDC Coronal Hole 165 is now crossing the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on June 26.

太陽風

The Earth is currently inside a slow solar wind regime, with solar wind speed around 350 km/s and an interplanetary magnetic field of 6nT. Similar conditions can be expected for the next 24 hours.

地磁

Geomagnetic conditions were quiet at planetary and unsettled at local levels (Kp up to 2, K_Dourbes 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 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.
