太陽活動區和耀斑

A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. We observed two M-class flares in the last 24 hours, both originating from SIDC Sunspot Group 885 (NOAA Active Region 4473), currently located at S09E68 with a Beta magnetic configuration. This sunspot group belongs to a complex group of recurring regions which are increasing solar activity as they rotate into view. The largest flare was a M2.6 flare (SIDC Flare 7982) peaking on June 21 at 02:46 UTC, which was produced by SIDC Sunspot Group 885 (NOAA Active Regions 4457, 4473). Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares likely and a small chance for X-class flares.

日冕物質拋射

The M2.6 flare (SIDC Flare 7982) from SIDC Sunspot group 885 (NOAA AR 4473) was associated with a faint west-directed, wide CME. Since this region is very close to the west limb, an Earth arrival of this CME is not expected.

太陽風

The Earth is currently inside a slow solar wind regime, with solar wind speed around 370 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, as measured by GOES-18 and GOES-19 was below the 1000 pfu alert threshold in the past 24 hours. The flux is expected to remain low over the next 24 hours. The 24-hour electron fluence was at normal levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.
