Bulletin
Solar activity was very low, without any significant flaring. NOAA active regions 2356 and 2357 are the only regions on the disk. No Earth- directed CMEs were observed.
Earth is inside a slow solar wind (speed around 350 km/s). The magnitude of the interplanetary magnetic field is around 5 nT. Geomagnetic conditions are quiet (K<4) and are expected to mainly remain so.
Today's estimated international sunspot number (ISN): 022, based on 10 stations.Solar indices for 30 May 2015
