Events
- John Adams Whipple and William Cranch Bond photographed the Moon in daguerreotype format using Harvard College's Great Refractor telescope. The daguerreotype was displayed at the Great Exhibition in Hyde Park later the same year. Given the fact that a full moon occurred on 1851-03-17T13:19+00, the daguerreotype's depiction of the Moon being slightly on the waxing gibbous side of a first quarter moon, subtracting 7.38 days from this time (25% of a Moon's synodic orbital period of 29.531 days), I estimate the time the photograph was taken was plus-or-minus a day around 1851-03-10T19:15-05, the rough time of Harvard College Observatory in Boston at 42° 22' 53.25" N, 71° 7' 42.14" W. The date of 1851-03-10 was determined using Stellarium, a digital planetarium package available in the Debian repository.

- 19:15-05 (24:15+00): Sometime on the local evening of 1851-03-10 at Harvard College's Great Refractor telescope in Boston, John Adams Whipple captured a daguerreotype of the Moon at a slightly waxing gibbous first quarter state. The date of 1851-03-10 was calculated given a full moon occurring on 1851-07-17T13:19+00 and comparing with a Stellarium simulation.
