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 C8.7 flare, peaking on 2026-06-23 at 23:25 UTC from SIDC Sunspot group 901 (NOAA AR4477). A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours, all having simple magnetic configuration (alpha or beta). Most of the C-class flaring was coming from SIDC Sunspot Group 901 (NOAA Active Region 4477) currently located at S13E64 and SIDC Sunspot Group 899 (NOAA Active Region 4475) currently located at S09E31. 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

The partial halo Coronal Mass Ejection (CME), with angular width of 130 degrees that first appeared in the SOHO/LASCO-C2 field of view at 23 JUN 19:15 UTC and directed to the northeastern quadrant is a back-sided event.

日冕洞

The equatorial negative polarity SIDC Coronal Hole 165 has finished it’s crossing over the central meridian. The northern mid latitude negative polarity SIDC Coronal Hole 142 is now crossing central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on June 27.

太陽風

The Earth is currently inside a slow solar wind regime, with solar wind speed around 450 km/s and an interplanetary magnetic field of 12nT, and BZ reaching a maximum negative value of -7nT. 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.
