Skywatch Line for Monday and Tuesday, November 10 and 11, 2025, written by Alan French
This is Dudley Observatory’s Skywatch Line for Monday and Tuesday, November 10 and 11, 2025, written by Alan French.
The Sun rises at 6:41 A.M. on Monday and sets at 4:37 P.M. On Tuesday it rises at 6:43 A.M. and sets at 4:36 P.M.
The Moon was full last Wednesday morning and is now moving toward last quarter, so a waning gibbous Moon rises late in the evening. Moonrise on Monday is at 9:39 P.M. in the east-northeast. Jupiter rose a little over an hour before the Moon, so the pair will travel together across the sky Monday night into Tuesday morning.
By midnight the Moon will be 22 degrees above the eastern horizon. It will be 60% sunlit and bright Jupiter will be 12 ½ degrees above and a bit right of the Moon. They will draw farther apart as the Moon moves eastward among the stars. By 5 A.M. Tuesday the pair will be separated by 14 ½ degrees. The Moon moves an average of about 13 degrees eastward among the stars each night.
The Moon will be high toward the south just before sunrise Tuesday morning, appearing 59% sunlit. The Moon sets at 12:54 P.M. Tuesday in the west-northwest. Look for a pale gibbous Moon against the blue sky just before Noon about 14 degrees above the western horizon. (A fist held at arm’s length spans 10 degrees across the knuckles.)
On Tuesday the Moon rises at 10:53 P.M. in the east-northeast. By midnight it will be 10 degrees high and Jupiter will be 25 ½ degrees away. The Moon reaches last quarter at 12:28 A.M. Wednesday. When the Moon sets at 1:20 P.M. Wednesday its visible face will be 45% in sunlight and it will be moving toward new.
Saturn remains well placed for viewing. It is due south and highest at 8:21 P.M. on Monday and 8:17 P.M. on Tuesday. It will be 43 degrees above the horizon. The rings are now tipped less than -0.6 degrees and, through a telescope, appear as a thin streak of light crossing the planet. If the seeing is poor and the image unsteady, the rings may be difficult to spot. Such thin rings are a rare sight and observing reports scarce, so I would welcome your reports.
Tiangong, the Chinese space station, crosses our skies Monday evening under dark skies. Look for it coming up from the western horizon at 6:03 P.M. It will be moving toward the north. By 6:04 it will be moving through Ophiuchus, and about 20 degrees above the west-southwestern horizon. Tiangong, shining at magnitude -1.2, will pass below Altair, in Aquila, the Eagle, at 6:05:30 (HH:MM:SS). It will move into the Earth’s shadow and fade from view just after 6:07 as it appears about to pass below Saturn in the southeast.
