      Sunspot region was practically invisible a couple of days ago. Now,
      it is naked-eye visible, and spans several Earth diameters end-to-end.
      A new sunspot region, region 613, has also rotated into view. The
      background X-ray flux has exhibited a slow but steady rise, and region
      609 has recently started exhibiting signs that it could be capable of
      generating a significant flare. Nothing yet, but stay tuned over the
      next several days.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 98
      SFI : 110
      A index : 6
      K index : 4

      Solar wind speed : 349.8 km/sec
      Solar wind density : 4.6 protons/cc
      Solar wind pressure : 1.0 nPa

      IMF : 6.9 nT
      IMF Orientation : 0.5 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. Region 609 has the
      potential to produce C-class events with a chance for an isolated
      M-class flare.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled with
      isolated active periods.

      Recent significant solar flare activity :
      None
