      The solar wind speed is creeping towards the 500 km/sec mark as a
      coronal hole generated solar wind stream makes its presence known.
      The solar wind speed could go higher over the next few days. What
      we're receiving now is something of a glancing blow from a coronal
      hole that's largely located in the southern hemisphere of the sun.
      However, there's another part of that large coronal hole complex that
      straddles the solar equator that's going to be in an Earth-pointing
      position very soon. Don't be surprised to see a spike in the solar
      wind speed along or about the 21st. There isn't much to report on the
      sunspot front this evening. There are seven small sunspot regions
      visible, but nine appear to have any flare generating potential at
      this time.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 148
      SFI : 137
      A index : 13
      K index : 2

      Solar wind speed : 460.6 km/sec
      Solar wind density : 6.0 protons/cc
      Solar wind pressure : 1.8 nPa

      IMF : 14.2 nT
      IMF Orientation : 1.1 nT South

      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 very low to low for the next three
      days.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be predominantly unsettled for
      the next three days.

      Recent significant solar flare activity :
      None
