Bulletin

There are four active regions on the visible disc. The X-ray background is on the C-level. NOAA AR 3112 produced an M1.5 flare peaking at 00:19 UT. More M-class flares can be expected for the next 24 hours.

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux was above the 1000 pfu threshold but has decreased below it in the last hours. It is expected to remain so in the coming 24 hours. The 24h electron fluence was at moderate levels in the past 24 hours and is expected to remain so in the next 24 hours.

The solar wind speed at the Earth has decreased in the last 24 hours to about 310 km/s. The interplanetary magnetic field magnitude has been around 5 nT. In the next 24 hours, similar conditions are expected.

Geomagnetic conditions were quiet to unsettled (Kp up to 2 and K_Dourbes up to 3). Similar conditions are expected for the next 24 hours.

Today's estimated international sunspot number (ISN): 082, based on 11 stations.
