      On the whole, there isn't very much happening tonight. The solar wind
      speed is still in the high 500's range, and the geomagnetic field
      remains somewhat unsettled. However, a persistent north-pointing
      Interplanetary Magnetic Field has been suppressing any strong
      geomagnetic activity, and aurora are not expected on a widespread
      scale as a result. With no significant coronal holes visible at this
      time, look for the solar wind speed to begin dropping off, and for
      geomagnetic activity stay pretty much in the unsettled category.
      There are three numbered sunspot regions visible. Of the group,
      region 471 looks to have the best chance for generating a significant
      flare, although it has been quiet for several days.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 93
      SFI : 113
      A index : 8
      K index : 4

      Solar wind speed : 577.8 km/sec
      Solar wind density : 2.1 protons/cc
      Solar wind pressure : 1.0 nPa

      IMF : 4.6 nT
      IMF Orientation : 0.6 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 remain at low levels. Region 471 has a
      slight chance of producing an isolated M-class flare.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to unsettled levels
      through the majority of the period. Day three may see elevated
      conditions due to a solar sector boundary crossing.

      Recent significant solar flare activity :
      None
