      It's a quiet weekend as the Earth is exiting a high-speed coronal hole
      solar wind stream. There are five sunspot regions visible, but none
      of them look to have the potential of generating a significant flare
      at the present time. A small coronal hole has appeared over the
      eastern limb of the solar disk, and it we could begin to see some
      solar wind gusts from along about the 18th.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 72
      SFI : 116
      A index : 5
      K index : 2

      Solar wind speed : 438.1 km/sec
      Solar wind density : 0.8 protons/cc
      Solar wind pressure : 0.3 nPa

      IMF : 2.3 nT
      IMF Orientation : 0.5 nT North

      GOES-12 Background X-ray Flux level : B1

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

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

      Solar Activity Forecast :
      Solar activity is expected to persist at very low levels.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled for the
      next three days.

      Recent significant solar flare activity :
      None
