    During the solar minimum, what's the longest period ever seen without sunspots on the sun, i.e., (days,weeks,months)?

    We only have data from human observers from about 1610. Shortly after observers began looking at the Sun with telescopes, the Sun essentially stopped producing sunspots for a period of roughly fifty years. There is some evidence that there were some sunspots during that time, and that the solar cycle continued, but the Sun produced VERY few sunspots, with high numbers around the solar maxima of 5-10.
