This is Ephemeris for Wednesday, October 30th. Today the Sun will be up for 10 hours and 14 minutes, setting at 6:33, and it will rise tomorrow at 8:20. The Moon, 2 days before new, will rise at 7:28 tomorrow morning.
Let’s take our weekly look at the whereabouts of the naked-eye planets. Venus can be spotted low in the southwestern sky by 7 PM, about half an hour after sunset. It will set at 8:18. Comet Tsuchinshan-ATLAS is definitely a binocular object and will be a third of the way up to the zenith in the southwest around 8 PM. It will set at 11:17 PM. Saturn will be in the southeast at 8 PM. Jupiter will rise at 8:42 PM in the east northeast, and be a good object for the small telescope about an hour later. By 7:00 AM tomorrow Jupiter will be high in the west southwest, among the winter stars, while Mars, which rises tonight near 11:30, will be high in the south.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). Times will be different for other locations.
Addendum
Venus in evening twilight, approximately half an hour after sunset. For the Grand Traverse area of Michigan that would be about 7 PM, October 30, 2024. Created using Stellarium.
Saturn, keeping company with Fomalhaut, the loneliest star in the sky in the south-southeastern sky at 8 PM. Created using Stellarium
Jupiter low in the east-northeast at 11 PM. Created using Stellarium.
Jupiter and Mars among the stars of winter seen at 7 AM tomorrow morning October 31, 2024. Created using Stellarium.
Telescopic Venus, Saturn and Jupiter (north up) as they would be seen in a small telescope with the same magnification. All the planets shown are for tonight, the evening of October 30, 2024. Apparent diameters: Venus 14.1″, 77.4% illuminated; Saturn 18.4″, its rings 42.8″, 5.2 degrees from edge on (opening up a bit); Jupiter 46.0″; Mars, too small to be represented here, is 9.2″. Saturn’s rings are actually much brighter than depicted here. The ” means seconds of arc, or 1/3600th of a degree. Created using Cartes du Ciel (Sky Charts).

This is a low precision ephemeris of the Sun Moon and naked eye planet positions for today and tomorrow, October 30 and 31, 2024. Some of the columns are self-explanatory, others not. The transit column is the time that the body crosses the meridian and is due south. Elong, for elongation, is the angle between the Sun and that body. RA is right ascension, which is the object’s east-west position on the celestial sphere in hours and minutes. Dec is declination which is the north-south position of the object on the celestial sphere in degrees and minutes. R is the distance of that object from the Sun in astronomical units. An astronomical unit is about 93 million miles or 150 million kilometers. And Delta is the distance of that object from the Earth, also in astronomical units. I omit the ‘m’ in am and pm for compactness. The data was generated using my LookingUp for DOS app and displayed as a table by my Ephemeris Helper app.
