There are eight active regions visible on the disk, a new region rotated over the east limb (NOAA AR 3413). They all have simple alpha or beta magnetic field configuration. Only C-class flares have occurred in the last 24 hours. The largest flare was a C4.7 flare peaking at 23:43 UTC on 21 August, from the new region. C-class flares are expected and M-class flares are possible (mostly from the new region), for the next 24 hours.
There were no Earth-directed Coronal Mass Ejections (CMEs) detected in the available coronagraph observations in the last 24 hours.
The solar wind speed at Earth has been declining in the last hours, it is now around 500 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). The solar wind speed is expected to further decrease in the next 24 hours.
During the last 24 hours the geomagnetic conditions were quiet (NOAA KP 1-2, K Bel 1-2). Similar conditions can be expected for the next 24 hours.
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.
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.
Today's estimated international sunspot number (ISN): 119, based on 20 stations.
