      As expected, the activity level has dropped dramatically since the
      departure of sunspot region 656. The sunspot number hasn't dropped,
      however, as there are four numbered sunspot regions visible. None of
      them, however, appear to have the ability to launch a significant
      flare for the time being. There is a small coronal hole that is now
      in an Earth-pointing position. We could see some solar wind gusts
      from it on or about the 22nd.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 88
      SFI : 120
      A index : 22
      K index : 3

      Solar wind speed : 472.8 km/sec
      Solar wind density : 1.0 protons/cc
      Solar wind pressure : 0.4 nPa

      IMF : 5.3 nT
      IMF Orientation : 4.7 nT South

      GOES-12 Background Solar X-ray flux : B2

      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 very low to low. Isolated C-class
      flares are possible.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to active with isolated
      minor storm periods.

      Recent significant solar flare activity :
      None
