Clear skies - Kurt ====================================================================== BAA electronic bulletin No. 00404 http://www.britastro.org/ ====================================================================== New Bright(ish) Supernova in Galaxy NGC 4088 Guy Hurst (TA Magazine) has recently issued an e-circular (Circular No. 2541) announcing a supernova discovery in galaxy NGC 4088. The SN, discovered by Giovanni Cortini, Italy, has been designated 2009dd and at discovery was at magnitude 13.7. This is relatively bright for a SN, and with the galaxy well placed in Ursa Major is an ideal opportunity for BAA members to monitor its increase or decrease in brightness over the next few nights. NGC 4088 is a magnitude 10.8 galaxy easily visible in a 20cm telescope although to see the SN will probably require a larger aperture. Imagers should have no trouble capturing the "new" star in a 20cm telescope. Note - galaxy NGC 4085 lies 12 arcmin south of NGC 4088. The SN lies at RA 12h 05m 33.6s and Dec +50d 32m 20s (2000.0), which puts it 2"W and 5"S of the centre of the galaxy (details taken from TA Circular).
