      The Earth is still inside a coronal hole solar wind stream this
      evening, and an aurora watch remains in effect. There were some
      beautiful aurora seen over Quebec, Canada on the night of July 6th.
      See this link for a great picture :

      Sunspot region 19 is a threat for producing M-class flares, as is
      sunspot region 30, which has just rotated into view. The enhanced
      solar wind speed and density were are now seeing are expected to last
      for at least the next 2 days.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 118
      SFI : 129
      A index : 8
      K index : 2

      Solar wind speed : 399.5 km/sec
      Solar wind density : 5.6 protons/cc
      Solar wind pressure : 1.4 nPa

      IMF : 6.5 nT
      IMF Orientation : 3.9 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 :
      Space weather for the next 24 hours is expected to be minor. Radio
      blackouts reaching the R1 level are expected.

      Solar activity forecast :
      Solar activity is expected to be low to moderate. Region 30 is a
      potential source of M-class activity.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled for the
      first day of the forecast period, then trend toward more active
      conditions by the end of the period, under the expected influence of a
      near-equatorial coronal hole.

      Recent significant solar flare activity :
