      Serving as proof once again that you don't necessarily need a strong
      flare to create a CME, a partial-halo CME shot off of the southwestern
      limb of the solar disk late yesterday. The most likely source was
      somewhere around sunspot region 8, although there were no significant
      flares recorded. The CME should be arriving here in about 2 days.
      Active geomagnetic conditions are a possibility at that time. The
      sunspot number remains unusually low for this time of the 11 year
      solar cycle.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 94
      SFI : 137
      A index : 6
      K index : 2

      Solar wind speed : 355.0 km/sec
      Solar wind density : 2.9 protons/cc
      Solar wind pressure : 0.6 nPa

      IMF : 3.9 nT
      IMF Orientation : 1.0 nT North

      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 :
      Geomagnetic field activity is expected to be at quiet to unsettled
      levels during the first half of the period. Mostly unsettled levels
      are expected during the latter half of the period in response to
      yesterday's partial halo CME.

      Recent significant solar flare activity :
      None
