在这项工作中，我们提出的光学R波段观测AO 0235+164在2006年11月至2012年12月期间使用的Ap 6 E CCD相机连接到主焦点的70厘米弯月望远镜在格鲁吉亚Abastumani天文台。在我们的监测期间，它显示了Δ R = 4.88 mag（14.19-19.07 mag）的大变化和Δ Tv = 73.5 min的短时间尺度。用周期分析方法对历史和我们观测的R波段资料进行分析，发现周期P1 = 8.26年，P2 = 0.54年。
In this work, we present optical R band observations of AO 0235+164 carried out during the period of November 2006 to December 2012 using the Ap6E CCD camera attached to the primary focus of the 70 cm meniscus telescope at Abastumani Observatory, Georgia. It shows a large variation of Δ R = 4.88 mag (14.19–19.07 mag) and a short time scale of Δ T v = 73.5 min during our monitoring period. When periodicity analysis methods are applied to the R-band data from both historic and our observations, periods P 1 = 8.26 yr and P 2 = 0.54 yr are found.
