As comparison star I would suggest the Tycho II 10.7 (0.4) star to the SE of RX. It is the middle one of the bright threesome to the South of RX. I have done CCD coverage last night but the data need processing still. Regards, Berto PS the position seems to be spot on, but that was established earlier already >>> Taichi Kato <tkato@kusastro.kyoto-u.ac.jp> 04/02/02 10:45AM >>> Re: RX J1155.4-5641 superoutburst > belated reporting on present S/O of RX J1155.4-5641. > > RXJ1155.4-5641 020330.768 122 MLF outburst > RXJ1155.4-5641 020401.740 109 MLF superoutburst The position of the object is: USNO0300.14373754 115527.034 -564153.26 (2000.0) 14.0 13.6 115527.0 -564153 (2000.0) RXJ1155.4-5641 13.6B CV 115527.6 -564148 (2000.0) 1RXS_J115527.6-564149 0.860 0.53 0.29 An apparent superoutburst was observed in 2001 January. The field is rich in Tycho-2 stars, which would be useful for CCD time-series photometry. Regards, Taichi Kato
