      ** Aurora Watch In Effect **

      The Earth is in a high speed solar wind stream coming from a coronal
      hole, although so far, there hasn't been much in the way of
      geomagnetic activity in response to it. Nevertheless, an aurora watch
      is in effect, and skywatchers in the higher latitudes should keep an
      eye out for aurora. After being completely devoid of sunspots not
      long ago, the sun is now peppered with seven numbered sunspot regions.
      Of the group, sunspot regions 782 and 783 are the largest, and are
      growing in size. Neither of them appear to have the magnetic
      complexity to generate a significant flare, but stay tuned. That
      could change.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 168
      SFI : 124
      A index : 16
      K index : 4

      Solar wind speed : 537.3 km/sec
      Solar wind density : 3.8 protons/cc
      Solar wind pressure : 1.2 nPa

      IMF : 4.2 nT
      IMF Orientation : 3.2 nT North

      GOES-12 Background X-ray Flux level : B3

      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 mostly low, but there is a chance for
      an isolated M-class during the next three days (3-5 July). Of the
      eight spotted regions on the disk, 785 and 783 appear to be the most
      likely sources for future M-class level activity.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be predominantly unsettled, but
      there is a continued chance for occasional active periods during the
      next two days (03-04 July) as effects from the coronal hole are
      expected to linger. Conditions should decline to mostly quiet by the
      third day (05 July).

      Recent significant solar flare activity :
      None
