Abstract

COMET 1870 II.—This comet was discovered on August 28, by Coggia in Marseilles, and was last observed by Pechüle in Hamburg. During the period of its visibility it described a heliocentric arc of about 59°. On September 26 it approached its least distance from the earth, this being measured as 0˙885 radii of the earth's orbit. In appearance the comet resembled a nebular mass with a perceptible nucleus; it varied, however, considerably, sometimes appearing without a nucleus, while at other times several nuclei were observed. Up to the present time the ephemeris obtained from the elements, computed by Gerst, represented very well the observed positions.
