      All is pretty quiet tonight. There isn't really much happening right
      this minute to speak of, although that might be changing soon. First,
      it is expected that the Earth will be moving into a high speed solar
      wind stream coming from a small coronal hole, possibly starting on the
      19th. Secondly, the background X-ray flux is rising rather quickly.
      The two sunspot regions currently in view, 699 and 701, haven't
      exhibited any signs of sudden activity, so its unlikely either one of
      them is the source. A better possibility is sunspot region 704, which
      is just now peeking over the eastern limb of the solar disk. As it
      comes into view over the next few days, we'll be able to get a better
      idea of what's in store.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 77
      SFI : 104
      A index : 2
      K index : 0

      Solar wind speed : 334.2 km/sec
      Solar wind density : 0.9 protons/cc
      Solar wind pressure : 0.2 nPa

      IMF : 5.6 nT
      IMF Orientation : 3.5 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 at very low to low levels.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at predominantly quiet to
      unsettled levels. Isolated active conditions may be seen at higher
      latitudes on 20 and 21 November due to coronal hole effects.

      Recent significant solar flare activity :
      None
