Abstract
THE Swedish observer, Mr. Nils Tamm, who discovered a nova of magnitude 8 in Aquila last month, has now detected another of these bodies in the same constellation. The latest nova was announced on October 20 as having been found on a plate taken on October 7, when the magnitude is stated to have been 7-0. Dr. W. H. Steavenson, who gives the position of the nova for 1936.0 as R.A. 19h 23m 28-16s, North Decl. 7° 28′ 32-5″, finds the magnitude to be about 8.0, with little fading between October 21 and 25. He reports the colour as being fiery red. In the spectrum the red line of hydrogen (Ha) is very bright and prominent, and contributes a large proportion of the total visual light of the nova. Tamm's earlier nova is still of about the eighth magnitude, after undergoing some marked fluctuations since its discovery. The two novae can just be seen simultaneously in a good prism binocular, being only a little more than six degrees apart.
