文摘

OI 090.4 was monitored on 21 nights from 2006 to 2012 for studying the variability. Strong variations occurred during the past 6 years. The long-term variability amplitude is consistent with previous results. Microvariability was analysed for 43 intra-night light curves. 30 out of 43 light curves showed microvariability by C and F test analysis.
