In 1990 and 1992, using the 60 cm reflector of Beijing Observatory, we carried out photoelectric UBV observations of the Be star EM Cep and obtained 277 data sets. After combining the published minimum times over the years we made the O — C analysi

This paper presents the result of UBV photoelectric photometry of VV Cephei. The contact times are determined from the B-V and U-B curves. The epoch of mideclipse is JD 2443361 in agreement with prediction. The unequal depths of the falling and risin

This paper gives the results of our photometric observations of ζ Aur during its 1979/80 eclipse in 6 narrow wave bands and in the UBV colours. Useful data were obtained on 31 nights covering all phases of the eclipse. Our narrow band observations e

Between 1980 December and 1984 March, we made photoelectric observations of SZ Lyn on 15 nights and recorded 19 times of maxima. Combining with those published, we now have a total of 139 times of maxima. Applying a second-order least squares reducti

ZB44 = G512, located at the top of the giant branch of M4, was first suspected to undergo fast light variation in 1975 by YAO Bao-an from photographic observations. It has now been observed photoelectrically with a 60-cm telescope, and the light vari

We present the result of UBV photometry and narrow-band photoelectric photometry of 44 i Boo made in January 1980 and March 1982, and we analysed the change in the orbital period of the binary over the past 65 years. We think that the fluctuations in
