Caroline Herschel comet discovery. Notes by German-British astronomer Caroline Herschel (1750-1848) on her observations of 17-18 April 1790, discovering her fourth comet, now known as Comet C/1790 H1 (Herschel). Caroline Herschel assisted her elder brother William, making her own observations between 1788 and 1797 from Observatory House in Slough, UK. She observed many nebulae, and discovered eight comets between 1786 and 1797. For her astronomical work she was awarded the Gold Medal of the Royal Astronomical Society in 1828. For a sequence of observations of this comet, see C024/9084 to C024/9086.
