      What a difference a few days makes! Gone are the geomagnetic storms
      and solar flares of sunspot region 720, and conditions are now just
      about as quiet as they can be. There are two small sunspot regions
      visible, 723 and 727, but neither appear to have the ability to
      generate significant flares at this time. By the way, in case anybody
      was wondering, a significant flare is a flare of M1.0 or higher.
      There are a couple of coronal holes that are rotating into an
      earth-pointing position, and we could start seeing high-speed solar
      wind gusts from them along about the 29th.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 46
      SFI : 89
      A index : 3
      K index : 0

      Solar wind speed : 307.8 km/sec
      Solar wind density : 0.4 protons/cc
      Solar wind pressure : 0.1 nPa

      IMF : 4.0 nT
      IMF Orientation : 0.3 nT South

      GOES-12 Background X-ray Flux level : A8

      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 remain at very low levels.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be at quiet to unsettled levels.
      There is a chance of isolated active conditions at high latitudes on
      27 and 28 January. Minor to major storming is possible on 29 January
      due to the onset of a recurrent high speed coronal hole stream.

      Recent significant solar flare activity :
      None
