Celebrate Maria’s Discovery of a Comet– October 1, 1847

10mo 1, 1847.  {October 1, 1847}   This evening at half past ten Maria discovered a telescopic comet five degrees above Polaris.  Persuaded that no nebulae could occupy that position unnoticed it scarcely needed the evidence of motion to give it the character of a comet.

From the journals of William Mitchell, father of Maria.

One hundred and seventy-one years later to the day!  In the year of her 200th birthday.
