太陽活動區和耀斑

Solar flaring activity was high over the past 24 hours, with 1 M-class flare identified. The largest flare was a M6.8 flare (SIDC Flare 7988) peaking on June 21 at 19:29 UTC, which was produced by SIDC Sunspot Group 885 (NOAA Active Regions 4473). A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 885 (NOAA Active Region 4473) ,currently located at S09E49, has a Beta-Gamma magnetic configuration and was in charge of the majority of the flaring activity of the past 24 hours.

日冕物質拋射

A Coronal Mass Ejection (CME), with angular width of 94 degrees, first appeared in the SOHO/LASCO-C2 field of view at June 21 20:00 UTC. The CME was associated with the M6.8 flare peaking on June 21 at 19:29 UTC (SIDC Sunspot Group 885/NOAA AR 4473), located S08E63. A type II radio burst was associated, indicating a speed of around 380 km/s. Seen the location on the disk there is a light possibility of a glancing blow late June 25.

日冕洞

A east-west elongated negative polarity mid-latitude coronal hole is crossing the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on June 25.

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.
