Two active regions (ARs) present on the visible solar disk. NOAA AR 2877 (beta magnetic field configuration) and 2880 (also beta). The former produced two C-class flare during the last 24 hours, with the strongest being a C1.8 flare peaking at 07:22 UT. Similar solar activity can be expected for the next 24 hours.

No Earth directed CMEs have been observed in the last 24 hours.

The greater than 10 MeV proton flux was at background levels in the past 24 hours, and is expected to stay there in the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold, no changes expected for the next 24 hours. The electron fluence was at normal levels over the past 24 hours, no changes expected over the next 24 hours.

The solar wind speed at the Earth has been around 420 km/s in the past 24 h, with magnetic field magnitudes around 5 nT. Similar conditions can be expected for the next 24 hours.

Geomagnetic conditions have been quiet to unsettled in the last 24 hours (NOAA Kp 0-2 and K Dourbes 0-3). Similar conditions are expected for the next 24 hours.
