11/27/2015 – Ephemeris – C/2013 US10 (Catalina)
Ephemeris for Friday, November 27th. The Sun will rise at 7:54. It’ll be up for 9 hours and 10 minutes, setting at 5:05. The Moon, 2 days past full, will rise at 7:12 this evening.
This Comet Catalina, and there are many Comet Catalinas has the unique designation C/2013 US10. This comet was found by the Catalina Sky Survey which looks for near Earth objects called NEOs, so there are lots of little Comet Catalinas running around. I’ll just refer to it as US10 in honor of the downstate highway. It’s like the comet with the unpronounceable name that the Rosetta spacecraft is orbiting is now known as 67P, and that new Kuiper Belt object 2012VP113 is known as Biden, because Joe Biden is our VP or Vice President. See we astronomers do have a sense of humor. We were hoping that US10 would reach naked eye brightness, but it’s under performing now appearing about half as bright as we thought it should be.
