    It s not often you see a Planetary K index of 0, but that s what we have tonight. That s just about as calm as you can get, folks! It s actually somewhat

      It's not often you see a Planetary K index of 0, but that's what we
      have tonight. That's just about as calm as you can get, folks! It's
      actually somewhat unexpected, given that the solar wind speed is
      hovering around the 400 km/sec mark, but a persistent north-pointing
      Imterplanetary Magnetic Field has been in place for several days. In
      about three days, however, activity should begin to pick up as the
      Earth moves inside of a high speed solar wind stream coming from a
      small coronal hole. None of the sunspot regions visible appear to
      have any significant flare generating potential at the present time.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 93
      SFI : 112
      A index : 4
      K index : 0

      Solar wind speed : 410.1 km/sec
      Solar wind density : 1.3 protons/cc
      Solar wind pressure : 0.4 nPa

      IMF : 5.4 nT
      IMF Orientation : 0.6 nT North

      Conditions for the last 24 hours :
      No space weather storms were observed for the past 24 hours.

      Forecast for the next 24 hours :
      No space weather storms are expected for the next 24 hours.

      Solar activity forecast :
      Solar activity is expected to be at very low to low levels.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to minor storm
      levels. The onset of a coronal hole high speed stream is expected on
      day three with minor storm conditions possible.

      Recent significant solar flare activity :
      None
