      There have been a pair of M-class flares in the past three days. One
      came from sunspot region 574 and one from region 578. Neither
      appeared to fire a CME in our direction. There is a small coronal
      hole that is in an Earth-pointing position, but it's located too far
      north on the solar disk to send us much in the way of high-speed solar
      wind gusts. The solar wind speed and density are slightly elevated
      tonight. Sunspot regions 574 and 578 have the potential for producing
      more M-class flares.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 82
      SFI : 114
      A index : 13
      K index : 3

      Solar wind speed : 405.6 km/sec
      Solar wind density : 6.4 protons/cc
      Solar wind pressure : 1.8 nPa

      IMF : 5.6 nT
      IMF Orientation : 1.6 nT North

      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 at very low to low levels with a
      slight chance of isolated moderate level activity. Region 578 has
      C-class flare potential and a small chance of an isolated M-class flare.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to unsettled levels.
      Isolated periods of active conditions may occur on 21 March,
      particularly during local night time hours.

      Recent significant solar flare activity :
      18-Mar-2004 2236Z M1.4
      18-Mar-2004 0517Z M1.6
