Not perfect seeing. I can just make out the Milky Way but only one star in the bowl of USA minor is visible. I make it out to about 8 seconds of arc. 8 _minutes_ of arc? That's very small? Few people here saying the comet is very large. Maybe the brightest part, the nucleus of the comet is 8 arc minutes? I went by the side of the comet I could see. I used the apparent distance between the nearby stars to estimate the size. It was exact where Luminos predicted. From the darker sky site I used for my first observation it might have been larger but you are observing from a city with light pollution maybe worse than my village. Getting in my car to observe the comet wasn’t an option last night due to early sampling of Christmas port. I went to a darker sky area a couple of miles away and the comet was easy in 10x50 binoculars but not visible with the naked eye. It was-1.5C and, as common at this time of year in Norfolk fog was beginning to form over the fields. I’m not good at estimating the brightness of extended objects like comets but it was less bright than the Orion Nebula and M31 and about 10 or 12 minutes of arc. The comet was also visible in the 8x40 binoculars I keep in the car for wildlife and bird watching. |
