Description

In the Oct. of 2000, we observed 10 gamma-ray loud blazars, PKS 0219+428 (3C 66A), PKS 0420-014 (OA129), S5 0716+714, 0754+100 (OT 090.4), 0827+243 (OJ 248), 1652+398 (Mrk 501), 2200+420 (BL Lacertae), 2230+114 (CTA 102), 2251+158 (3C 454.3), and 2344+514, with the 70 cm optical telescope at Abstumani Observatory, Georgia. We found intraday variations in PKS 0420-014, S5 0716+714, BL Lacertae, and CTA 102. A variation of 0.3 magnitude over a time scale of about 3 hours was observed in R band in BL Lacertae on JD 2451827. We did not detected variation from 3C 66A, Mrk 501, 3C 454.3 or 2344+514 during our observational period. For the TeV gamma-ray source 2344+514 no clear variation was detected in an observational period of two weeks
