      It was one year ago yesterday that Columbia was lost on re-entry.
      Today's solar activity report is dedicated to Columbia and her crew.

      May their adventure forever continue. Rest in peace.

      ** Aurora Watch In Effect **

      The solar wind speed is still on the high side of 600 km/sec tonight,
      and G-1 geomagnetic storm conditions have been observed within the
      last 24 hours. Therefore, an aurora watch remains in effect.
      Skywatchers in the higher latitudes should keep an eye out for aurora.
      The elevated geomagnetic conditions are expected to persist for
      another 48 hours as the Earth travels through a high speed coronal
      hole solar wind stream. There are three numbered sunspot regions
      visible. While all of them have been relatively quiet thusfar,
      regions 547 and 549 have at least an outside chance of generating a
      significant flare.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 106
      SFI : 102
      A index : 28
      K index : 3

      Solar wind speed : 624.2 km/sec
      Solar wind density : 3.8 protons/cc
      Solar wind pressure : 2.4 nPa

      IMF : 7.1 nT
      IMF Orientation : 5.1 nT South

      Conditions for the last 24 hours :
      Space weather for the past 24 hours has been minor. Geomagnetic storms
      reaching the G1 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 low for the next three days (2-4
      February). There is a slight chance for an isolated M-flare from
      Region 547 or Region 549.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be unsettled to active for the
      next two days (3-4 February), and should decline to mostly unsettled
      with occasional active periods for the third day (5 February). The
      enhanced activity is expected from favorably positioned coronal holes.
