Abstract:
We present the first extensive photometric results of CL Aur from our
BVRI CCD photometry made on 22 nights from 2003 November to 2005
February. Fifteen new timings of minimum light were obtained. During
the past 104yr, the orbital period has varied due to a periodic
oscillation superposed on a continuous period increase. The period and
semi-amplitude of the oscillation are about 21.6yr and 0.0133-day,
respectively.
Description:
New photometric observations of CL Aur were obtained using a SITe 2K
CCD camera and a BVRI filter set attached to the 61cm reflector at
Sobaeksan Optical Astronomy Observatory (SOAO) in Korea. The
observations of the first season were made on 14 nights from 2003
November to 2004 March and those of the second season on 8 nights from
2004 December to 2005 February.
