КомментарийC/2014 Q2 Lovejoy January 15th 23:00 UT 25X100 Binoculars 25X SQM 15.66 Alt 40 M1 4 I knew the moment I looked up that the seeing was not so good over our house. When the Milky Way is clearly visible and M31 is naked eye then it's as good a sky as possible for me at home. Lovejoy 's coma appeared very round , and there was the now familiar material streaming off to the left. No tail visible , no colour visible in the coma , not naked eye . The central mass seemed duller than my observation earlier in that same 24 hrs at 00:16 UT, but that could be down to the seeing at the time. My eye picked up on the colour of a star in a little triangle of stars HIP 15777 a KO star which was a tad orange and another lovely star in the fov was blue , HIP 16268 . HIP 15951 was also slightly yellow/orange. This sidetrack of noticing star colour has prompted me to pay more attention to star spectra. I intend to buy some more gel pens to add those stars in their apparent colours to future drawings. I think that is why I love comets so much as following them across the sky is always a journey of many discoveries and interesting learning paths.
