      To say that things are quiet would be an understatement, but that in
      itself is something to talk about. There is a single, very small
      sunspot region visible, and there are no significant coronal holes
      visible. The background X-ray flux has been holding in the low A
      range for several days, and the X-ray plot has periodically been
      showing something you don't often see...an absolutely flat line. No
      flares of any kind at all. Not even very small ones. The solar flux
      has dropped below 80, which is also something you don't often see.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 11
      SFI : 78
      A index : 9
      K index : 3

      Solar wind speed : 380.9 km/sec
      Solar wind density : 2.0 protons/cc
      Solar wind pressure : 0.5 nPa

      IMF : 7.1 nT
      IMF Orientation : 1.3 nT South

      GOES Background X-ray Flux Level : A3

      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.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled.

      Recent significant solar flare activity :
      None
