The solar wind speed has dropped to 470km/s as the influence of the fast stream wanes, and whereas on previous rotations a second fast stream had led to active/minor storm conditions this stream was far weaker during the last rotation and we do not expect any such effects during the next few days. Solar activity is expected to remain low to very low with neither of the active regions presently on the solar disk holding much potential for even isolated events.
