Gore — On Suspected Variable Stars. 375 



1^0. 478. Lacaille 6514 Lupi. — 6m. Lacaille. Gould says: "There 

 is small room for doubt that the magnitude of this star varies from 

 near 5-5- m. to 6^ m. ; but there are not yet suilicient data to fix the 

 limits or period" {V. A. p. 278.) 



JSTo. 479. Lalande 28716 Seepentis. — 6 m. Lalande ; 6-7 Heis. 

 Not in Argelander's Uranometria ; 6*1 Gould. My suspicion of vari- 

 ability rests on my own observations, which are as follows : — 



Sept., 1877, Lalande 28716 equal to A Serpentis (4-5 Heis). 



April 21, 1878, distinctly less than X. 



April 5, 1883, More than a magnitude less than A.. About three 

 steps brighter than 40 (6-7 Heis), or about 6-1 m. 



April 20, 1883. Seems a little less than 6 m., or about 6-2. 



April 30, 1883. About 6 m. — visible to naked eye. 



Possibly, however, X may be the variable — perhaps of the Algol 

 type. 



ISTo. 479«. — LiBE^.— See Ast. NacJi., No. 2434. 



No. 480. Anon Coeon^ Boeealis. — Included by Schonfeld in his 

 provisional list. He says, " Vergieichstem zu E.. Coronfe, schwankt 

 nach Schmidt zwischen 11 m. und 13-12 m. AN 80-1912 Meine Beo- 

 bachtungen geben gleiehfalls eine schwache Yeranderlichkeit in engeren 

 Grenzen." Schmidt found a period of 1^ to 2 months. 



No. 481. 5248 B. A. C. Deaconis. — In Comptes Rendus, vol. xxvii. 

 p. 113, are the following remarks with reference to this star : "jt? by a 

 star yellow - 1™ 0^-73 and 5'53"-2 further n. Both visible to the naked 

 eye ; but Argelander in Uranometria Nova only shows the yellow star. 

 In Argelander's zone observations 5248 is 5 m., and the yellow 6 m. 

 Both were observed at Oxford in June, 1845. No magnitude is given 

 to 5248, but the yellow observed 3 times of 6-7 and once 7 m.; whereas 

 M. Butillon's repeated observations makes its magnitude 5^." 5 m. 

 Heis; 6 m. Franks, April 21, 1878 {^'private letter'). My observations 

 are as follows : — 



November 24, 1878. About ^ a magnitude brighter than the star 

 to the north, but nearly one magnitude less than a star s/ (5 m. Heis) ; 

 October 5, 1879. About the same as above; April 8, 1883. About 

 one step brighter than the star to the n, and about equal to a 6 m. 

 (Heis) nf. 



No. 482. Lacaille 6546 NoEM.a; ( Uranometria Argentina, p. 269). 



No. 483. p Seepentis.— 4 m. Lalande; 5 Harding; 5 Heis; 5^ 

 Franks, 1878. I found it brighter than Lalande 28993 (5^ m.) 

 April 21, 1878; also brighter than 26 Serpentis (6 m. Heis). 



No. 484. Lacaille 6536 Apodis. — 7 m. Lacaille. The Cordoba 

 estimates show fluctuations of brightness from 6-7 to 7*4, or perhajjs 

 through a greater range ( U. A., p. 243).
