11/28/2019 – Ephemeris – This is the best time to spot Mercury in the morning

November 28, 2019 Comments off

Ephemeris for Thanksgiving Day, Thursday, November 28th. Today the Sun will be up for 9 hours and 8 minutes, setting at 5:05, and it will rise tomorrow at 7:57. The Moon, 2 days past new, will set at 6:59 this evening.

The planet Mercury is at its greatest western elongation from the Sun this morning. Being west of the Sun it rises first. It being a planet inside the Earth’s orbit it appears to swing from the east side to the west side of the Sun, from the evening to the morning side of the Sun. It never appears outside of twilight around here. For the next week it will be going away from us, and becoming more illuminated by the Sun from our perspective, and actually is getting brighter. Then it will seem to fall back, actually moving around and behind the Sun. This evening the thin sliver of the Moon will appear near brilliant Venus. The best time to look is around an hour after sunset, which is about 6 p.m. Venus will set at 6:43 p.m.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.


Mercury for the next week

Mercury in the morning, about an hour before sunrise (7 a.m. here) for the next week. The aspect of its orbit changes for two reasons, sunrise time is advancing a bit, and the Earth is changing its position with respect to Mercury and its orbit, and Mercury too is moving.
