Reims, France — 13 February 1849
Star moving in the sky with sudden accelerations
Skilled amateur observer Coulvier-Gravier observed an unusual “star” at 7:30 P.M. It was a 3rd magnitude object first seen in the vicinity of Delta Cephei. It moved through a course of 20 degrees in the sky, with sudden accelerations and stops (“saccades”).
