      This past weekend saw some brief G-1 geomagnetic storm activity as the
      Earth moved through a high-speed coronal hole solar wind stream,
      although there were no reports of aurora. There is but a single small
      sunspot region visible. The sunspot cycle seems to be progressing as
      expected towards the expected minimum, which should come in early
      2006. There is a coronal hole coming into view, and we should begin
      to see some high-speed solar wind stream effects along about April 4th.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 15\
      SFI : 79
      A index : 4
      K index : 2

      Solar wind speed : 443.1 km/sec
      Solar wind density : 3.5 protons/cc
      Solar wind pressure : 1.0 nPa

      IMF : 7.1 nT
      IMF Orientation : 2.3 nT South

      GOES-12 Background X-ray Flux level : A2

      Conditions for the last 24 hours :
