      Just about anytime now, the Earth should be coming into a high-speed
      solar wind stream coming from a coronal hole. At this moment, the
      solar wind speed is slightly elevated, but that's about it. We might
      see some isolated G-1 geomagnetic storm conditions on Wednesday and
      Thursday, and the possibility exists for high latitude aurora. Stay
      tuned. That's really about the only thing noteworthy for the time
      being. There are two numbered sunspot regions visible, but neither
      appear to have the potential to generate a significant flare at the
      present time.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 63
      SFI : 87
      A index : 11
      K index : 2

      Solar wind speed : 428.3 km/sec
      Solar wind density : 6.3 protons/cc
      Solar wind pressure : 1.3 nPa

      IMF : 8.7 nT
      IMF Orientation : 8.3 nT North

      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 atcivity forecast :
      Solar activity is expected to be very low to low. Region 601 may
      produce C-class flares.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to active with isolated
      minor storm conditions on days one and two (5-6 May) as a coronal hole
      high speed wind stream moves into geoeffective position. Activity
      should subside to quiet to unsettled levels on day three (7 May).

      Recent significant solar flare activity :
      None
