Abstract
FAYE'S COMET.—Dr. Axel-Möller commences his ephemeris of Faye's comet for the present year on July 1, when its distance from the earth will be 2.005, and that from the sun 2.53; the perihelion passage will not take place till January 22, 1881. The intensity of light corresponding to the comet's distances on July 1 is 0.039; in 1844 it was observed with sensibly the same intensity, the value for the last observation with the 15-inch refractor at Pulkowa being 0.035. The comet attains its greatest brightness in the middle of October, when the value corresponds to that at the last observation in 1858, with the 9.6-inch refractor at Berlin on October 16. At discovery by M. Faye in 1843 the theoretical intensity of light was 0.54, which has not been approached at any of the subsequent returns. The following positions are taken from Dr. Axel-Moller's ephemeris, which is calculated for Berlin midnight, or about 11h. G.M.T.:—
