论文摘要
提出了从2018年4月至2020年9月收集的年轻恒星对象V2492 CYG的BV（RI）C光度观察结果。这些观察结果是我们对2010年始于2010年开始并持续迄今为止的恒星监视的一部分。 V2492 CYG位于鹈鹕星云中，其可变性是通过积聚和灭绝事件来解释的。新的光度数据表明，恒星在所有频段中都表现出快速的不规则变异性。在2019年3月至2020年5月的那个时期，我们在V2492 CYG的光曲线中进行了延长的减小事件。
Results from the BV(RI)c photometric observations of the young stellar object V2492 Cyg collected in the period from April 2018 to September 2020 are presented. These observations are a part of our monitoring of the star that began in 2010 and continuing to date. V2492 Cyg is located in the Pelican Nebula, and its variability was explained by both accretion and extinction events. The new photometric data show that the star continues to exhibit rapid irregular variability in all bands. In the period from March 2019 to May 2020, we registered a prolonged decrease event in the light curve of V2492 Cyg.
