      The Earth is inside of a high speed solar wind stream, but it isn't
      having much of an effect. While being high speed, it is also quite
      tenous, at about one proton per cc. That isn't dense enough to have a
      significant effect on the geomagnetic field. There are currently four
      small sunspot regions in view, with a fifth on the verge of rotating
      into view. None of the ones currently visible have the abilitty to
      generate a significant flare at this time. Don't be surprised if G-1
      geomagnetic storm conditions appear briefly over the next couple of
      days, but I don't expect to see anything major, and aurora seem
      unlikely for now.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 63
      SFI : 114
      A index : 18
      K index : 2

      Solar wind speed : 623.7 km/sec
      Solar wind density : 1.4 protons/cc
      Solar wind pressure : 1.1 nPa

      IMF : 3.6 nT
      IMF Orientation : 0.5 nT North

      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 very low to low.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to active on 11
      February. Expect quiet to unsettled conditions on 12 and 13 February
      as the coronal hole stream moves out of geoeffective position.

      Recent significant solar flare activity :
      None
