      The last 24 hours have seen G-2 geomagnetic storm activity associated
      with the arrival of a faint, partial-halo CME from a long duration
      C-class flare which occurred on the 8th. We could see the same thing
      again on the 14th or 15th as another partial-halo CME from another
      long duration C-class flare arrives on the scene. Sunspot regions 775
      and 776, the only two numbered sunspot regions currently visible, are
      approaching the western limb of the solar disk. However, they still
      have the ability to generate a significant flare, and there are still
      a few days before they rotate completely out of view, so don't write
      them off just yet.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 73
      SFI : 92
      A index : 30
      K index : 2

      Solar wind speed : 453.1 km/sec
      Solar wind density : 2.4 protons/cc
      Solar wind pressure : 0.8 nPa

      IMF : 4.9 nT
      IMF Orientation : 0.2 nT North

      GOES-12 Background X-ray Flux level : B1

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been moderate. Geomagnetic
      storms reaching the G2 level occurred.

      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 very low to low.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be mostly unsettled on 14 June.
      The arrival of a CME associated with C-class X-ray activity early on
      12 June is expected early on 15 June causing unsettled to active
      conditions with periods of minor storming possible. Activity is
      expected to settle down to quiet to active levels on 16 June.

      Recent significant solar flare activity :
      None
