摘要：
3C 66A is one of our first batches of photometric monitoring objects with the 1 m optical telescope at Yunnan University Astronomical Observatory.In the present work,the observational campaign was performed from 2021November 1 to 2022 February 27 in the Johnson-Morgan system V and R bands.The average magnitudes in each band were ■=15.52±0.18 mag and ■=15.07±0.17 mag.The overall variability amplitudes were ΔV=■,Amp=70.27% and ΔR=■,Amp=68.56%,respectively.Most of the intraday variabilities(IDVs) occurred in 2021 December and 2022 February.The minimal rise/decay timescale was about 6 minutes(5.82±2.74 minutes and 6.18±2.81 minutes on 2022 February 11,6.99±3.70 minutes and 6.17±2.91 minutes on 2022 February 12).Durations of these rapid variabilities were from 11.99 to 179.67 minutes.The discrete correlation function analyses between V and R bands showed significantly correlated variability.Color index analysis of ID Vs showed that the spectrums do not change with variabilities.
