It was a cold and moonlit morning here in Essex, but I decided to find a darkish spot near the SE Essex marshes and image comet 2013US10 Catalina. My 200mm telephoto lens and a stack of 16 x 10 second exposures recorded the dust and gas tails. The image at 05.52hrs UT was squeezed in at the start of astronomical twilight but before the sky brightened too much. The comet was only 5 degrees above the horizon at the time of the image. When the comet moves further away from the Sun it should be a good one!
