      Things are relatively quiet tonight, which is an exception to the rule
      of how solar and geomagnetic activity has been of late. Sunspot
      region 386 has been calm since it fired of an M6.8 flare on the 17th.
      It does still, however, appear to have the ability to produce a major
      flare. All of the recent activity has produced some beautiful aurora.
      See this link for some great aurora pictures that have been captured
      throughout the month of June, especially the 14th - 18th.
      http://science.nasa.gov/spaceweather/aurora/gallery_01jun03.html . If
      the forecasts pan out, there could be some more aurora activity
      starting Saturday night as high-speed solar wind gusts from a coronal
      hole arrive at Earth.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 121
      SFI : 117
      A index : 14
      K index : 4

      Solar wind speed : 567.2 km/sec
      Solar wind density : 1.8 protons/cc
      Solar wind pressure : 0.7 nPa

      IMF : 6.8 nT
      IMF Orientation : 2.7 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 range from low to moderate levels.
      Region 386 remains capable of producing an isolated major event.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at predominantly unsettled
      levels. Active conditions may exist especially at high latitudes
      beginning late on day two with the return of a recurrent coronal hole
      high speed stream.

      Recent significant solar flare activity :
      None
