      All remains quiet tonight, as there isn't much happening to speak of.
      The solar wind speed could edge upward a bit starting tomorrow due to
      the influence of a small coronal hole that is in an Earth-pointing
      position. There are three numbered subspot regions visible. While
      none look to have the potential of generating a significant flare at
      this time, sunspot region 564 has been growing rapidly, and now spans
      more than 5 Earth diameters end-to-end. The background X-ray flux is
      also beginning to show some signs of activity, so stay tuned over the
      next few days.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 52
      SFI : 98
      A index : 6
      K index : 1

      Solar wind speed : 383.1 km/sec
      Solar wind density : 4.0 protons/cc
      Solar wind pressure : 0.9 nPa

      IMF : 7.5 nT
      IMF Orientation : 2.6 nT South

      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 levels.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to unsettled levels.
      Isolated active conditions are possible, due to a small and variable
      high speed stream.

      Recent significant solar flare activity :
      None
