      Activity is beginning to pick up as a new active sunspot region,
      reegion 634, is rotating into view. It has already fired off an
      M-class flare, and the background X-ray flux has risen significantly.
      Region 634 isn't in a position yet to see exactly how big it is or
      what sort of magnetic complexity it has, but that will change over the
      next few days. There's also a small coronal hole that has rotated
      into an Earth-pointing position. We should begin seeing the high
      speed colar wind gusts from it on or about the 18th.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 55
      SFI : 95
      A index : 9
      K index : 3

      Solar wind speed : 319.6 km/sec
      Solar wind density : 1.0 protons/cc
      Solar wind pressure : 0.2 nPa

      IMF : 8.4 nT
      IMF Orientation : 8.3 nT South

      GEOS-12 Background X-ray Flux level : B3

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been minor. Radio blackouts
      reaching the R1 level occurred.

      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. Another small
      M-class flare is possible in Region 634.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled becoming
      unsettled to active under the influence of a high-speed coronal hole
      stream.

      Recent significant solar flare activity :
