It displays a decrease in brightness levels in the V-band, decreasing by 0.77 magnitude within 1.7 hours. It has also been noted to show one rapid outburst which was followed by a faded state from 17.57 to 18.20 in V-band frequencies. In the R-band, it has shown another outburst within the time range of 2.2 hours in December 1988.Xie G. Z. Li K. H. Cheng F. Z. Lu R. W. Liu B. F. Hao P. J. Liu Z. H.
