      There are a total of five numbered sunspot regions visible, one of
      them naked-eye visible. However, none of them have the potential for
      producing any significant flares. The only thing that migght break
      the current monotony is a coronal hole that has rotated into an
      Earth-pointing position. We should begin to see high-speed solar wind
      gusts from it along about the 18th. The coronal hole, however, is
      relatively small, so don't expect to see anything major out of the event.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 69
      SFI : 122
      A index : 3
      K index : 2

      Solar wind speed : 422.1 km/sec
      Solar wind density : 1.9 protons/cc
      Solar wind pressure : 0.6 nPa

      IMF : 5.8 nT
      IMF Orientation : 2.9 nT North

      GOES-12 Background X-ray Flux level : B1

      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 low for the next three days.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled for
      tomorrow (February 16). Mostly unsettled conditions are expected on
      February 17 and unsettled to slightly active conditions are expected
      on February 18. The increase is anticipated in response to a favorably
      positioned coronal hole.

      Recent significant ssolar flare activity :
      None
