Comet Schwassmann-Wachmann 3 in that day has been positioned about 5.7 degrees east of Arcturus. The component C has a visual brightness of about 10th magnitude, visible only with portable binoculars. But it was bad transparency condition, I could not observe its dust tail clearly. The component B can be observed about 2.5 degrees WNW of compopnent C with its brightness of about 13th magnitude.
And this image shows you one more component of 15th magnitude G just northwest of component B for the first time.
