摘要：

In this work, we report the observations of the long-period comet C/2015 O1 performed on2018 January 29–30 and April 13 with the Nanshan 1-meter wide-field telescope operated by Xinjiang Astronomical Observatory. We obtain the morphological features of C/2015 O1 using an image enhancement method, and calculate the dust-activity parameter Afρ and the coma color based on photometric analysis. An obvious fan-shaped structure was observed at different observation times. We find that the activity of C/2015 O1 gradually decreases as the comet advances toward perihelion and the observed B-V and V-R colors are consistent with those of other comets.
