After no sunspots over the entire month of February, sunspot group
2734 appeared on March 5. So far the new sunspot numbers are 14, 17,
and 14 on March 5-7. I believe this was the longest consecutive
period (33 days) with no sunspots on this declining side of Cycle
24. The polarity of the new sunspot group identifies it as being
from Cycle 24, not the upcoming Cycle 25.
