Bulletin
Solar activity is low, no C-class flares in past 24 h. NOAA AR 2390 has beta-gamma magnetic field configuration and could produce C-class flares.
The Earth is under the influence of a fast speed stream emanating from a coronal hole, solar wind speeds are around 600 km/s with interplanetary magnetic field magnitudes of 5 nT. Active conditions were observed overnight and more active periods can be expected in the next 24 hours.
