August 21, 2019 1 comment

Ephemeris for Wednesday, August 21st. Today the Sun will be up for 13 hours and 47 minutes, setting at 8:39, and it will rise tomorrow at 6:53. The Moon, 2 days before last quarter, will rise at 11:41 this evening.

Let’s look at the planets for this week. Mars and Venus are too close to the Sun to be seen. Mars is still on the evening or east side of the Sun, as is Venus which passed superior conjunction with the Sun a week ago. Bright Jupiter will be in the southern sky as it gets dark. With steadily held binoculars a few of the 4 largest satellites of Jupiter can be seen. Four of Jupiter’s largest satellites can be spotted in telescopes tonight. Jupiter will set at 1:04 a.m. Saturn, the ringed planet, will be in the southern sky in the evening. It will pass the meridian, due south at 10:45 p.m. and will set at 3:12 a.m. Mercury will rise at 5:44 a.m. in the east-northeast.

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

08/20/2019 – Ephemeris – To find Sagittarius, look for the Teapot

August 20, 2019 Leave a comment

Ephemeris for Tuesday, August 20th. Today the Sun will be up for 13 hours and 49 minutes, setting at 8:40, and it will rise tomorrow at 6:51. The Moon, 3 days before last quarter, will rise at 11:16 this evening.

Due south and low in the sky at 10:30 p.m. now is one of my favorite asterisms the Teapot of the constellation Sagittarius. Sagittarius classically represents a centaur with a bow and arrow aimed at the heart of the constellation Scorpius to its west. I can find the bow and arrow here, but the half man half horse figure of the centaur eludes me. However the stout little teapot of the children’s song is quite obvious, with its base, lid on top, handle to the left and the spout to the right. To make things more realistic the bright Milky Way seems to rise like steam from its spout. As the night goes on the Teapot slides westward and appears to tilt, pouring its tea on the southwestern horizon. Saturn this year is above and left of it.

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

The same is true for Saturn’s moons, however Titan is much brighter than the other moons. Created using Cartes du Ciel (Sky Charts).

07/26/2019 – Ephemeris – Scorpius the starry scorpion crawls over the southern horizon

July 26, 2019 Comments off

Ephemeris for Friday, July 26th. Today the Sun will be up for 14 hours and 53 minutes, setting at 9:15, and it will rise tomorrow at 6:23. The Moon, 2 days past last quarter, will rise at 2:11 tomorrow morning.

There’s a large constellation located low in the south at about about 11 tonight. It’s Scorpius the scorpion. Its brightest star is Antares in its heart, a red giant star, that I get calls about from time to time as being a UFO. With bright Jupiter above and left of it, it won’t be as noticeable. From Antares to the right is a star then a vertical arc of three stars that is its head. The Scorpion’s tail is a line of stars running down to the left of Antares swooping to the horizon before coming back up and ending in a pair of stars that portray his poisonous stinger. There is a beautiful star cluster seen in binoculars at that first bend in the tail that is unfortunately too low to appreciate from this far north. I was very impressed with it when spotting it from the Florida Keys when I was down there in 1986 observing Halley’s Comet.

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

Addendum

Animated finder chart for Scorpius the scorpion for 11 p.m. July 26, 2019. A year from now Jupiter will be just pass where Saturn is, and Saturn will be just off the frame of this image. Also note the “Teapot” asterism of Sagittarius just left of the scorpion with the Milky Way as steam rising from its spout.
