Remarks: Days in brackets () => lower probability of activity
         (or lower accuracy of) forecast, depending on previous
         development on the Sun. In addition especially at this
         time of the solar cycle, space weather conditions are
         frequently determined by short timescale events, usually
         not able to be forecasted.
