Bulletin
Solar activity is low, no C-class flares in past 24 h. NOAA AR 2390 has now a beta-gamma configuration of its magnetic field, and can therefore produce C-class, and even (although not likely) M-class flares.
Geomagnetic conditions have ranged from quiet to unsettled, with solar wind speeds around 450 km/s and interplanetary magnetic field magnitudes of 5 nT. Similar conditions are expected for the coming 48 h.
