太陽活動區和耀斑

There are eight active regions visible on the disk. They all have simple alpha or beta magnetic field configuration. Only C-class flares were observed in the last 24 hours. The strongest flare was a C1.5 with peak at 23:47 UTC on 23 August, from NOAA AR 3405. For the next 24 hours, C-class flares can be expected.

日冕物質拋射

There were no Earth-directed Coronal Mass Ejections (CMEs) detected in the available coronagraph observations in the last 24 hours.

太陽風

The Earth is inside a slow solar wind stream, with speed around 430 km/s and an interplanetary magnetic field around 5 nT. The interplanetary magnetic field orientation was predominantly in the negative sector (field directed towards the Sun). Similar conditions can be expected in the next 24 hours.

地磁

During the last 24 hours the geomagnetic conditions were quiet to unsettled (NOAA KP 1-2, K Bel 1-3). Similar conditions can be expected for the next 24 hours.

質子通量水平

Over the past 24 hours the greater than 10 MeV GOES proton flux was 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 remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain so in the next 24 hours. The 24 hour electron fluence was at normal levels and is expected to remain so.
