Nikolai Ivanovich Lobachevsky

Birth time unknown. Wikidata records the date and place but not the clock time of birth, so this is a noon chart: the Ascendant, Midheaven and house placements are omitted, and the Moon (which moves ~12–14° per day) is approximate. Sun and the slower planets are reliable to the sign. Date precision: Wikidata records this birth to the month (stored as the 1st), so the day shown may be approximate and the Sun sign can differ if the true date falls near a sign boundary.
