    A new sunspot -- number 1001 -- emerged on Thursday, September 11. It is actually a single group with two small magnetic disturbances; we hope it is not another like the last sunspot, a weak one that barely emerged on August 21-22. That spot was so small

    For several days over the past week, we saw a couple of sunspots -- but just like other recent dying Solar Cycle 23 spots, they faded quickly. This group, lasting from July 18-20, was number 1000. No sign of Solar Cycle 24 in recent memory, just a couple

    Another week and still no sunspots. The 3-month moving average for daily sunspot numbers that we began reporting toward the end of Solar Cycle 23 seemed to retrospectively suggest that solar minimum occurred last fall. The daily average for the 3-month pe
