Abstract
A STAR WITH LARGE PROPER MOTION.—In Astronomische Nachrichten, No. 4674, Miss E. F. Bellamy dirccts attention to the large proper motion of Helsingfors 914, which was found when assisting the Vatican Observatory in the reductions of its portion of the Astrographic Catalogue (zones +65° to +55°). The star is close to Hels. 913, and since the seconds of R.A. in the Helsingfors Catalogue for 914 and 913 are 44·8s. and 44·2s., whereas in BD they differ by 5s., and the Vatican residuals also differed by nearly 5s., it was at first thought that there was a mistake in Helsingfors. Subsequent investigation showed that Hels. 914 had a considerable proper motion, the motions being +0·236s. and +0·36″ annually. Miss Bellamy points out that the centennial proper motion in arc of a great circle is +157·0″, the largest proper motion hitherto found in either the Oxford or Rome work, the next largest being 141·9″.
