------------------------------------------------------------------- THE ASTRONOMER Electronic Circular No 1369 1998 Dec 30 14.20UT Ed:Guy M Hurst, 16,Westminster Close, Kempshott Rise, Basingstoke, Hants, RG22 4PP,England.Telephone/FAX(01256)471074Int:+441256471074 INTERNET: GUY@TAHQ.DEMON.CO.UK GMH at AST.STAR.RL.AC.UK WORLD WIDE WEB http://www.demon.co.uk/astronomer ------------------------------------------------------------------- TAV J0218+507 (=Q1998/073) Mike Collins, Everton, Beds, England reported a probable variable on 1998 Oct 12 (logged as Q1998/073) which was located at: RA 02h18m21s DEC +50 46' 03"(2000) The object was detected on photographs for the UK Nova/Supernova Patrol. On 1988 Sept 20 Mike estimated it at magnitude 10.5 but 11.4 on a shot of 1989 Dec 26.0UT. The star was not in the Guide Star Catalogue. At the request of the editor, Tom Boles imaged it CCD (unfiltered) on 1998 Oct 14 and Dec 27. Analysis by Tom showed the star fading from 9.8 to 10.5. The Dec 27 exposure received over the Internet by the editor clearly showed the object to be the SE component of a double. The editor identified the suspect on the Palomar Sky Survey of 1953 Nov 20 (Red plate) and reduced the magnitude as 13.8. A patrol photograph by Tony Poole of 1978 Feb 2 (20h43mUT) showed it at magnitude 12.3 on Kodak 2475 film. \\\\\\TAV J0218+507 b found by Mike Collins S,400,6,S -C, 2.3057, 50.7653,2000 O,200,200,10.5,(14? -T,Mira?
