Additional Information


  • Christoph Arnold (December 17, 1650 - April 15, 1695) was a German amateur astronomer. Interested in astronomy, he spotted the great comet of 1683, eight days before Hevelius did. He also observed the great comet of 1686. In 1686, Kirch went to Leipzig. There, he observed the great comet of 1686, together with Gottfried Kirch. There, Kirch met his second wife, Maria Margarethe Winckelmann (1670-1720), who had actually learned astronomy from Arnold. Arnold observed the transit of Mercury in front of the sun on October 13, 1690. For this work, he received some money and a tax exemption from the town of Leipzig. He was the author of Göttliche Gnadenzeichen, in einem Sonnenwunder vor Augen gestellt (Leipzig, 1692) which contains an account of the transit of Mercury in 1690.
