      There hasn't been any more significant flare activity since the single
      M3.3 outburst from sunspot region 735. In fact, the two visible
      numbered sunspot regions are on the verge of rotating over the western
      limb of the solar disk. Look for the sunspot number to drop even
      lower than it is if nothing else comes into view. There is a rather
      large coronal hole that has rotated into an Earth-pointing position.
      We should see some high speed solar wind gusts from it about the end
      of the week.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 23
      SFI : 92
      A index : 6
      K index : 1

      Solar wind speed : 351.0 km/sec
      Solar wind density : 0.6 protons/cc
      Solar wind pressure : 0.2 nPa

      IMF : 9.8 nT
      IMF Orientation : 5.5 nT North

      GOES-12 Background X-ray Flux level : B1

      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 levels throughout the period.

      Geomagnetic acctivity forecast :
      The geomagnetic field is expected to be at quiet to unsettled levels
      through 23 February. A recurrent high speed coronal hole stream should
      become geoeffective on 24 February. Active conditions are possible on
      24 and 25 February due to the coronal hole influences.

      Recent significant solar flare activity :
      None
