      the position of this sunspot leads me to believe it is a member of the last cycle...unless the image is inverted.

      i believe the spots from the new cycle should be originating in the northern hemisphere.

      i will verify this assumption and reply to the group.

      Thanks Mike, good catch. This may be the real start of the next solar
      sun spot cycle. The Sun has been very quiet for all those who ran out
      and purchased a PST for the last few years.

      By the way we do show the Sun's current EIT (Extreme ultraviolet Imaging
      Telescope) image on our home page.
