Observations of Sun Spots, 1739-1743

Eleven-page notebook containing John Winthrop's handwritten observations and calculations. Titled by Winthrop "Observations of 'Spots' on ye Sun with ye Naked Eye," this is the first known record of his scientific observations and records what he saw while examining the sun "with an 8 foot telescope from 6 a.m. til sun set" on the Boston Commons and concluding with "a considerable aurora borealis" that night (April 20, 1739). It has been speculated that his reference to the aurora borealis in these observations may indicate that he recognized the interrelation of the aurora borealis and sun spots, a concept which was not definitively established until the mid-nineteenth century.
