Abstract
VARIABLE STARS.—Mr. J. E. Gore (Umballa, Punjâb) writes, under date May 5, that he believes 27 Canis Majoris to be a variable star. It is 4 in Harding's Atlas, but at present about 51/2 or 6, and much inferior to 28 in the same constellation, which Harding rates at 5. The change of brightness was first noticed in 1874. This star is 4.5 in the Radcliffe Catalogues, 5 in Arg. Zones, 51/2 in Lacaille, and 6.5 in Heis's Catalogue; Behrmann has 6, and the lowest estimate of magnitude is 7, in Flamsteed's Catalogue, with respect to which Baily remarks that there is no magnitude recorded in the original observation-book, and that modern observations make it 41/2. Mr. Gore states he has also “suspected some variation of light in the red star 22 Canis Majoris (between δ and ɛ); it is usually rated as of magnitude 3 or 31/2, but for some time past it has seemed rather fainter than an ordinary star of the fourth magnitude.” Bradley and Piazzi have this star 3.4, Flamsteed, Brisbane, and Heis, 4, the Washington General Catalogue 5, and it is so rated once by Argelander; in Behrmann it is 4.5.
