Supernova 2008S Discovered by Ron Arbour |

|
 Ron Arbour, General Adviser to the BAA Deep Sky Section, has a habit of discovering supernovae during the first 2 or 3 months of the year and his latest continues this trend, SN 2008S being discovered on the evening of 2008 Feb 01. Lying in galaxy NGC 6946, a magnitude 9 spiral straddling the border between Cepheus and Cygnus at RA 20h 34.8m and Dec +60o 09’ (2000.0), the 17th mag SN is offset 53.1” west and 195.5” south of the galaxy centre.
This discovery was made using his 30cm Schmidt-Cass. and Starlight Xpress CCD camera. It was announced on CBET (Central Bureau Electronic Telegram) 1234 and on TA Electronic Circular 2416, from which some of this information is taken. Confirmatory images were obtained by Tom Boles (Coddenham, Suffolk). To give some idea of the work involved in supernova searching; on this particular night Ron was patrolling from early evening until 02.30 the following morning and acquired over 900 images - each needing to be individually checked. For anyone wanting to carry out a supernova patrol on just one galaxy there are not many better choices than NGC 6946 as 9 SN have now been discovered here since 1917.
Congratulations to Ron on his 19th discovery.
