Right ascension: 15h 15m Declination: 42° 0'
Constellation: Boötes
Date/time: 2010.05.13 0:20 UT
Equipment: 12" f/5 Newtonian

Description:

Tiny, extremely faint object. The core is barely brighter, not starlike. I estimate an average visual surface brightness of 14.6m and a dimension of 2' x 0.8'. Unfortunately the bad seeing is not ideal for its observation
