太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours, all having alpha or beta magnetic configuration. SIDC Sunspot Group 693 (NOAA Active Region 4284), turning towards the west limb, and SIDC Sunspot Group 705 (NOAA Active Region 4290), turning on disk from the east limb, were the most active regions responsible for the majority of the C-class flaring. The largest flare was a C4.8 flare (SIDC Flare 6159) peaking on November 22 at 11:46 UTC from SIDC Sunspot Group 705 (NOAA Active Region 4290). 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

A elongated positive polarity coronal hole, mainly mid- latitude but with an equatorial extension, is crossing the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on November 25.

太陽風

Slow solar wind conditions were recorded over the past 24 hours. The interplanetary magnetic field was around 7 nT. The Bz reached a minimum value of - 2nT. The solar wind velocity was around 430 km/s. Slow solar wind conditions are expected in the next 24 hours.

地磁

Geomagnetic activity was globally and locally quiet to unsettled over the past 24 hours. Geomagnetic conditions are expected to be quiet to unsettled in the next 24h.

質子通量水平

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days.

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.
