The comet C/2017T2 PanSTARRS in that day was positioned at southwestern edge of Camelopardalis, moving along the autumnal Milky Way. The brightness of coma has reached about 9th magnitude. You can detect the greenish ionized composition surrounding the coma. I could estimate the length of dust tail in south direction as over 12 arc minutes from the image.
