    One could be forgiven for snoozing a bit. Solar and geomagnetic conditions have been pretty boring. But, such is live near the bottom of the sunspot cycle.

      One could be forgiven for snoozing a bit. Solar and geomagnetic
      conditions have been pretty boring. But, such is live near the bottom
      of the sunspot cycle. That is not, however, to say that nothing will
      happen until we start into Cycle 24, which should be in 2007. For
      whatever reason, there is a tendency for some big flares to come at
      the bottom of the cycle. That won't be happening in the forseeable
      future, though, as things are quiet tonight. There are two small
      sunspot regions visible, but neither has the potential of generating a
      significant flare at this time. The Earth will be moving into a
      high-speed coronal hole solar wind stream soon, so there is a chance
      of some increased activity over the next few days.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 30
      SFI : 96
      A index : 4
      K index : 1

      Solar wind speed : 367.3 km/sec
      Solar wind density : 8.1 protons/cc
      Solar wind pressure : 1.6 nPa

      IMF : 6.0 nT
      IMF Orientation : 1.8 nT South

      GOES-12 Background X-ray Flux level : A3

      Conditions for the last 25 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 predominantly unsettled to
      active levels throughout the period. Isolated minor storming may be
      possible on 3 and 4 April. The expected elevated conditions are due to
      a recurrent coronal hole high speed stream.

      Recent significant solar flare activity :
      None
