      The new year is starting off quiet. The high speed solar wind of a
      week ago has died down. There are two small sunspot regions visible
      this evening. Neither has the potential for generating a significant
      flare. Both are close to the western limb of the solar disk. If
      nothing else rotates into view, we could be looking at a blank solar
      disk in a couple of days. Speaking of the solar disk, if you measured
      it with the right equipment, you'd notice it's a little larger. The
      Earth reached perihelion today, at 147 million km from the sun. No
      coronal holes are in view, so barring something really unusual, look
      for conditions to remain quiet for several days. By the way, if you
      long for the days of the solar max, spaceweather.com has put every
      aurora picture they have in one gallery. Some of the pictures are
      breathtaking.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 25
      SFI : 84
      A index : 1
      K index : 0

      Solar wind speed : 345.0 km/sec
      Solar wind density : 0.9 nPa
      Solar wind pressure : 0.2 nPa

      IMF : 5.9 nT
      IMF Orientation : 0.3 nT South

      GOES-12 Background X-ray Flux level : A3

      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 continue very low.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to mildly unsettled. The
      slight increase later in the period is due to the possible effects of
      a high speed solar wind stream.

      Recent significant solar flare activity :
      None
