| 英文摘要 | CCD photometric data for 10 BL Lacertae objects are given. The main results are the following: 1) A short timescale variability exists for OI 090.4 with a characteristic time of 80 minutes and an amplitude of DELTA-B = 0.56 mag (+/- 0.11 mag). 2) An outburst of 0.72 mag (+/- 0.1 mag) within 40 minutes has again been recorded in the V band for ON+231; its morphology strongly resembles that of the two previously reported outbursts of 1987 and 1988. 3) A large amplitude outburst of 0.87 mag (+/- 0.10 mag) within 96 minutes has been recorded for OJ-131 in the B band. 4) Evidence of a correlation between colour index B - V and B has been obtained for OI 090.4 and OJ-131. The spectrum appears flatter when the source is brighter. 5) Evidence for relativistic beaming in 6 BL Lacertae objects is discussed. |
