The comet 2009K5 McNaught in that day has been positioned in area of Cepheus with a declination of 82 degrees, now moving its celescial path of the most northern part. It was bad sky condition with thin clouds covered, I could not capture the detailed structure of comet. But it had a coma brightness of about 8th magnitude, almost same with it observed a week ago.
