Abstract
THE NEW STAR IN CYGNUS. —Prof. Schmidt has published details of his observations of this star from November 24, the date of discovery, to December 15, and has also put upon record the dates, between November 1 and 20, when he had examined the constellation Cygnus, with the view to show that a star as bright as the fifth magnitude could not have escaped his notice, and therefore that the rise of the new one to the third magnitude must have been very rapid, as also appears to have been the case with T Coronæ in 1866. On the evening of its discovery the star was strong golden yellow, and writing on December 9, Herr Schmidt states it had always been of a deep yellow, but at no time exhibited the redness of its neighbour, 75 Cygni. The following are the magnitudes on different nights as determined at Athens by careful comparisons with ρ, π2, τ, ζ and Φ Cygni, and η Pegasi: —
