      While solar activity remains very low, the solar wind speed has topped
      the 500 mark, and there was actually a G-1 geomagnetic storm within
      the last 24 hours as a result of the increased solar wind speed. No
      aurora pics on spaceweather.com yet, but I wouldn't be surprised if a
      few show up that were taken in the higher latitudes. The appearance
      of two small sunspot regions has raised the sunspot number a little,
      but nothing looks like it will be generating any significant flares.
      We're getting closer to the bottom of the sunspot cycle, which is due
      in Jan of 07. There will be spikes of activity along the way, and
      don't be surprised to see a big flare at or near the bottom. For
      reasons nobody really understands, that seems to be the pattern.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 38
      SFI : 91
      A index : 25
      K index : 2

      Solar wind speed : 505.8 km/sec
      Solar wind density : 4.2 protons/cc
      Solar wind pressure : 1.5 nPa

      IMF : 3.8 nT
      IMF Orientation : 0.5 nT South

      GOES-12 Background X-ray Flux level : A8

      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. Region 682 may produce C-class
      flares.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to active on 15 October,
      from the residual effects of the coronal hole high speed solar wind
      stream. Activity should subside to quiet to unsettled levels on 16-17
      October.

      Recent significant solar flare activity :
      None
