      The Earth is still inside of, but exiting a coronal hole solar wind
      stream. As anticipated, it didn't have much of an effect. There
      really isn't much to talk about tonight. There are two small sunspot
      regions visible, but neitther is a flare-producer. Perhaps worthy of
      note is the fact that sunspot region 720, the source of a lot of major
      flares not long ago, is making its away across the back side of the
      sun, and so far, appears to be holding together pretty well. If it
      stays together, which is certainly possible for a big sunspot, it
      could be back for a return engagement in about a week. Stay tuned.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 27
      SFI : 84
      A index : 6
      K index : 1

      Solar wind speed : 493.5 km/sec
      Solar wind density : 2.0 protons/cc
      Solar wind pressure : 0.8 nPa

      IMF : 7.5 nT
      IMF Orientation : 0.8 nT South

      GOES-12 Background X-ray Flux level : A4

      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. The activity level is
      expected to increase after 05 February when old Region 720 returns to
      the visible disk.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to continue at quiet to unsettled

      Receent significant solar flare activity :
