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 8 numbered sunspot groups were identified on the disk over the past 24 hours. NOAA ARs 3828 (beta), and 3833 (beta) and 3835 (beta-gamma) were the most active ARs in the last 24 hours. NOAA AR 3836 produced the strongest flare of the day, a C4 flare with peak at 07:56 UTC, this AR has a beta-gamma magnetic field configuration and has grown in size in the last hours. 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

No Earth directed CMEs were observed in the past 24 hours.

太陽風

Solar wind conditions at Earth show the arrival of the expected (mild) high speed stream from a positive polarity equatorial coronal hole, with solar wind speed up to 550 km/s. The interplanetary magnetic field reached 12 nT and Bz down to -10 nT. In the next 24 hours, more disturbed solar wind conditions can be expected with the possible arrival of a glancing blow from the CME from 22 September.

地磁

The geomagnetic conditions over the past 24 hours reached minor levels both globally and locally (Kp and K_Bel from 3 to 5). Up to moderate storm conditions could occur in the next 24 hours due to an ICME arrival.

質子通量水平

Over the past 24 hours, the greater than 10 MeV GOES proton flux has been at nominal levels, and is expected to remain so over 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 16 and GOES 18 has been below the 1000 pfu threshold in the last 24 hours. It is expected to remain so over the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so over the next 24 hours.
