      Sunspot regions 634 and 635 are approaching the western limb of the
      solar disk. While both regions are quite large and naked-eye visible
      (never look directly at the sun!!), and also seem to have the magnetic
      complexity to generate a significant flare, they've been quiet. The
      background X-ray flux has been holding steady at B2, and about the
      strongest flare we've gotten in the last few days is a C-2 event.
      There is a coronal hole that has rotated into view, and it will soon
      be in an Earth-pointing position. Look for some solar wind gusts from
      it to arrive on or about the 29th.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 104
      SFI : 113
      A index : 4
      K index : 2

      Solar wind speed : 361.1 km/sec
      Solar wind density : 4.4 protons/cc
      Solar wind pressure : 0.7 nPa

      IMF : 4.1 nT
      IMF Orientation : 3.6 nT South

      GOES-12 Background X-ray Flux level : B2

      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 to moderate levels. Region 635
      continues to exhibit the potential to produce an M-class flare.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to unsettled levels
      through 24 June. Active conditions are expected on 25 and 26 June due
      to a recurrent coronal hole high speed stream.

      Recent significant solar flare activity :
      None
