Caroline Herschel's eight comets were published between 28 August 1782 to 5 February 1787. Five of her comets were published in "Philosophical Transactions of the Royal Society". William was even summoned to Windsor Castle to demonstrate Caroline's comet to the royal family. William recorded this phenomenon himself, terming it "My Sister's Comet." She wrote letters to the Astronomer Royal to announce the discovery of her second comet, and wrote to Joseph Banks upon the discovery of her third and fourth comets.
