      The Earth has crossed into a high-speed solar wind stream coming from
      a coronal hole. At the initial boundary crossing, G-1 geomagnetic
      storm conditions were noted. Even though summer is not a good time
      for aurora, aurora were seen and photographed in Canada. This is the
      first time we've seen aurora in quite awhile. Here's the obligatory
      picture, taken in Quebec.

      As of right now, the Earth is in the process of exiting the solar
      wind stream, so any more aurora sightings are unlikely. Expect the
      solar wind speed to slow down over the coming days. There are two
      small sunspot regions visible. At the present time, neither one
      appears to be capable of generating a signigicant flare.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 26
      SFI : 81
      A index : 19
      K index : 3

      Solar wind speed : 486.0 km/sec
      Solar wind density : 2.5 protons/cc
      Solar wind pressure : 1.0 nPa

      IMF : 4.3 nT
      IMF Orientation : 3.7 nT North

      GOES-12 Background X-ray Flux level : A3

      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 remain at very low levels.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled. Isolated
      active periods are possible on 02 - 03 July as the high speed coronal
      hole stream subsides.
