Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was very low. Region 1017 (N18E17) remains a Bxo beta spot group. This region was relatively quiet, however, it has increased slightly in sunspot count. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: Geomagnetic field activity was at quiet levels. IIB. Geophysical Activity Forecast: Geomagnetic field activity is expected to be predominately quiet for the next three days (15 - 17 May). III.
