      G-1 geomagnetic storm conditions have been observed within the last 24
      hours, although there hasn't been any mention of any aurora caused by
      the event. The solar wind speed is staying in the mid-500's range,
      and likely will remain there or higher in the days ahead. There's a
      decent-sized coronal hole that's rotating towards an Earth-pointing
      position. Expect to see the solar wind speed kick up on or about the
      28th. There are several sunspot regions visible on the solar disk
      tonight. At this time, none of them appear to have the potential for
      producing a significant flare. So far, the SOHO satellite is still
      sending data back, but that will probably change later on this week as
      a result of SOHO's high-gain antenna pointing problems. If that
      happens, the ability to see coronal holes may be lost as long as the
      SOHO blackout period lasts, which should be around 18 days.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 131
      SFI : 115
      A index : 29
      K index : 3

      Solar wind speed : 566.6 km/sec
      Solar wind density : 2.1 protons/cc
      Solar wind pressure : 1.6 nPa

      IMF : 4.7 nT
      IMF Orientation : 2.2 nT North

      Conditions for the lastr 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 continue at low levels. Several of the
      active regions on the visible disk have potential to produce
      occasional C-class flares.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to active with isolated
      minor storm periods at high latitudes.

      Recent significant solar flare activity :
      None
