      ** Aurora Watch In Effect **

      While the solar wind speed is currently down in the low 400's for the
      time being, that's likely to change over the next couple of days. A
      pair of coronal holes has rotated into an Earth pointing position, and
      we should be picking up the high speed solar wind gusts from in ont eh
      26th or 27th. An aorora watch is in effect. How much geomagnetic
      activity will result is always uncertain, but stay tuned! The suspot
      number remains quite low tonight, and only two numbered sunspot
      regions are visible. Neither region looks to have much
      flare-generating potential, although there's at least an outside
      chance for an M-class flare from region 290.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 48
      SFI : 102
      A index : 5
      K index : 1

      Solar wind speed : 405.0 km/sec
      Solar wind density : 5.7 protons/cc
      Solar wind pressure : 1.7 nPa

      IMF : 9.3 nT
      IMF Orientation : 4.3 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 be at very low to low levels for the
      next three days.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled for the
      next three days.

      Recent significant solar flare activity :
      None
