At spaceweather.com it was stated that sunspot 1029 (just about to
transit out of view) is a Cycle 24 sunspot. Could any solar
astronomers out there comment on whether its latitude is unusual for
this stage of the cycle? My understanding was that "new cycle"
sunspots typically appear at high latitudes, and "old cycle" spots
appear near the solar equator.
Thanks for any information. |

If you look at the diagram here:
http://en.wikipedia.org/wiki/File:Sunspot-bfly.gif
you will see that "typically at high latitudes" covers a range from
below 15 to above 30. A sunspot at 14-17N
http://www.swpc.noaa.gov/ftpmenu/forecasts/SRS.html
is just at the low end of it.
