      The sunspot number has edged up above 200 this evening for the first
      time in a while, and there are now five numbered sunspot regions
      visible. So far, the only that looks to have and real flare-producing
      potential is region 296. That could change, however, so stay tuned.
      The solar wind speed looks to be taking a bit of a respite from the
      high speed profile it has exhibited of late, and the speed is down in
      the low 400's for the time being. While aurora weren't widespread,
      there were some quite beautiful aorora spotten in Alaska and Canada
      during the period of March 3-5. See this link for some great aurora
      pictures :

      There is another coronal hole just now rotating into view of the
      eastern limb of the solar disk. It's not in view enough to see what
      it's really like quite yet, but look for the possibility of another
      round of high speed solar wind in about a week.

      The current solar and geomagneti cconditions are :

      NOAA sunspot number : 203
      SFI : 148
      A index : 11
      K index : 2

      Solar wind speed : 432.8 km/sec
      Solar wind density : 4.0 protons/cc
      Solar wind pressure : 1.1 nPa

      IMF : 4.3 nT
      IMF Orientation : 4.0 nT South

      Conditions for the last 24 hours :
      No space weather storms were observed for the past 24 hours.

      Forecast for the nbext 24 hours :
      No space weather storms are expected for the next 24 hours.

      Solar activity forecast :
      Solar activity is expected to be at low levels. There is a small
      chance for an isolated M-class flare from Region 296 (N13W31).

      Geomagnetic activity forecast :
      The geomagnetic field is expected to continue at quiet to unsettled
      levels throughout the period.

      Recent significant solar flare activity :
      None
