......Over the past several years, the sun has been entering another minimum in the 11-year sunspot cycle. However, the unforeseen and lingering absence of sunspots during the past year has raised concerns that another period like the Dalton Minimum could occur. The number of sunspots in 2008 was the 7th fewest since 1749, averaging only 2.9 sunspots/day. The most recent year with fewer sunspots was 95 years ago in 1913.
