Bulletin

The X-ray flux background has been at the C level in the last 24 hours. NOAA AR 3112 (beta-delta magnetic field configuration) produced an M1.0 flare, peaking at 00:47 UT. C-class flares are expected and M-class flares are possible in the coming 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 has been above the 1000 pfu threshold in the last 24 hours, it is expected to remain elevated in the coming 24 hours. The 24h electron fluence was at normal to 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 is still relatively fast around 500 km/s, it reached 620 km/s in the last 24 hours. The interplanetary magnetic field magnitude has been around 5 nT. In the next 24 hours, a gradual transition from fast to slow solar wind is expected.

Geomagnetic conditions reached active levels (both Kp and K_Dourbes up to 4). Mostly unsettled to active levels expected in the next 24 hours.

Today's estimated international sunspot number (ISN): 115, based on 22 stations.
