Comet Brooks, formally designated as C/1893 U1, is a non-periodic comet that became visible through telescopes in late 1893. This comet might be the parent body of the Gamma Normids meteor shower (alongside C/1864 R1).
Discovery and observations
William Robert Brooks spotted a new comet on the morning of 17 October 1893 from his observatory in Geneva, New York. At the time of discovery, it was a 7th-magnitude object located within the constellation Virgo. One day later, Edward E. Barnard made follow-up observations of the comet, noting it had a deformed tail about 4 degrees long. Barnard continued his photographic sessions of the comet throughout November 1893, documenting its changes in structure. It was last observed by Herbert C. Wilson on the evening of 26 January 1894.
