V485 Cen
 
Preliminary analysis of the data (3-hr started at
1997.05.17,024 UT, 1-hr started at 1997.05.19,260 UT, 5-hr started at
1997.05.19,969 UT, and 6-hr started at 1997.05.20,964 UT) collected with
the 1.3-m Warsaw telescope at Las Campanas Observatory as a subproject
of the OGLE-2 project indicates that this star belongs to the SU UMa
group of cataclysmic variables. The well-developed typical superhumps
with amplitude 0.25 mag on the first night and 0.15 mag on the last
night have period 60.6 min. Taking into account value of 59 min. for the
orbital period given by Augusteijn et al (A&A, 311, 889) the period
excess is 2.7%.
