1933 Tinchen, provisional designation 1972 AC, is a Vestian asteroid from the inner regions of the asteroid belt, about 5 kilometers in diameter. It was discovered on 14 January 1972, by Czech astronomer Luboš Kohoutek at the Hamburger Bergedorf Observatory in Germany, who named it after his wife, Christine Kohoutek.[2][10]
