Comet 90001396 414P/STEREO Observation Details
414P/STEREO Daily Motion
414P/STEREO will not be observable tonight. It will reach its transit at 24° by 08:23 and set at 12:45. Throughout the night, from 16:24 to 03:41, it will be below the horizon. 414P/STEREO will rise again after sunrise, at 04:00.90001396 414P/STEREO will be visible until January, 1, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.
