      For the past few days, the Earth has been inside of a high speed solar
      wind stream coming from a coronal hole. On Wednesday night, at the
      height of the geomagnetic activity, aurora were spotted in North
      Dakota, northern Europe, and Alaska! See thus link for some
      impressive pictures :
      http://science.nasa.gov/spaceweather/aurora/gallery_01feb03.htm . The
      solar wind speed is dropping off now as Earth exist the high speed
      stream. However, more activity will be here in a few days, thanks to
      another coronal hole following close on the heels of the one just
      departed. We should be seeing the high speed solar wind gusts from it
      along about 3/4. After an extended period of time with only very
      small sunspot regions, we have what appears to be a pretty large one
      just now coming into view. Sunspot region 296 is rotating over the
      eastern limb of the solar disk, and will merit watching in the days ahead.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 77
      SFI : 125
      A index : 18
      K index : 1

      Solar wind speed : 430.1 km/sec
      Solar wind density : 4.2 protons/cc
      Solar wind pressure : 1.1 nPa

      IMF : 4.4 nT
      IMF Orientation : 1.1 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 low levels for the next three days.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at unsettled to active levels
      as the high speed coronal hole stream continues.

      Recent significant solar flare activity :
      None
