04/17/2019 – Ephemeris – Let’s look for the bright planets

April 17, 2019 Comments off

Ephemeris for Wednesday, April 17th. Today the Sun will be up for 13 hours and 34 minutes, setting at 8:30, and it will rise tomorrow at 6:53. The Moon, 2 days before full, will set at 6:53 tomorrow morning.

Let’s look at the planets for this week. Mars will be in the western sky this evening, above the V-shaped stars of the face of Taurus the bull. It will set at 12:23 a.m. In the morning sky we have Jupiter, in Ophiuchus, which will rise tomorrow at 1:07 a.m. in the east-southeast. Saturn will be next to rise at 2:54 a.m., also in the east-southeast. It is in Sagittarius. Venus will rise at 5:56 a.m. again in the east-southeast. By 6:30 in the morning they will be strung out from the south down to the eastern horizon. Venus will remain in our morning sky, though more difficult to see until August when it passes behind the Sun to enter the evening sky. Tiny Mercury may be glimpsed a bit left and just below Venus in the bright twilight.

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

03/06/2019 – Ephemeris – Looking at the bright naked eye planets for this week

March 6, 2019 Comments off

Ephemeris for Ash Wednesday, March 6th. Today the Sun will be up for 11 hours and 25 minutes, setting at 6:36, and it will rise tomorrow at 7:10. The Moon is new today, and won’t be visible.

Let’s look at the planets for this week. We have two evening planets visible now. Tiny and elusive Mercury is really hard to spot low in the west from about 7 p.m. until it sets at 7:52 p.m. It is fading fast. Binoculars are the only way to spot it now. Mars will be in the west-southwestern sky this evening and will set at 11:42 p.m. Mars too is fading. In the morning sky we have Jupiter which will rise tomorrow at 2:45 a.m. It is second to Venus in brightness. Saturn will be next to rise at 4:32 a.m. It will be to the upper right of Venus which will rise at 5:32 a.m. tomorrow. By 6 in the morning they will be string out from the southeast to the south. They will be a beautiful sight as morning twilight advances.

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

Ephemeris for Wednesday, February 27th. Today the Sun will be up for 11 hours and 3 minutes, setting at 6:27, and it will rise tomorrow at 7:22. The Moon, 1 day past last quarter, will rise at 3:46 tomorrow morning.

Let’s look at the planets for this week. We have two evening planets visible now. Tiny and elusive Mercury should be visible low in the west from about 7 p.m. to about 7:45 p.m. It should be visible for the next few days. Binoculars are a big help in spotting it. Mars will be in the west-southwestern sky this evening and will set at 11:44 p.m. In the morning sky we have Jupiter which will rise tomorrow at 3:05 a.m. It is second to Venus in brightness. Saturn will be next to rise at 4:57 a.m. It will be to the upper right of Venus which will rise at 5:31 a.m. tomorrow. In small telescopes Saturn will show its rings and Venus will show a small slightly gibbous moon shape which will shrink and grow more full over the next months

02/26/2019 – Ephemeris – Mercury at greatest eastern elongation from the Sun tonight

February 26, 2019 Comments off

Ephemeris for Tuesday, February 26th. Today the Sun will be up for 11 hours even, setting at 6:26, and it will rise tomorrow at 7:24. The Moon, at last quarter today, will rise at 2:49 tomorrow morning.

This evening the planet Mercury is at its greatest distance from the Sun to the east by an angle of 18 degrees. It’s called greatest eastern elongation from the Sun. Mercury has a very elliptical orbit of the Sun, and right now it’s near its closest to the Sun called perihelion, of 28.6 million miles (46.1 million km). In late winter and spring the ecliptic, the path in the sky that the planets appear near, meets the horizon at a steep angle near sunset, which allows us to see planets near and east of the Sun more easily. The same is true for the planets west of the Sun in the morning in the fall. Southern hemisphere observers see Mercury best when its is at aphelion, farthest from the Sun, 66 percent farther away.

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

Addendum

Northern hemisphere elongation of Mercury in the spring.

Looking at Mercury at greatest eastern elongation tonight February 26, 2019 from Northern Michigan displaying its orbit with a transparent horizon at sunset. Notice how lopsided the orbit appears, extending farther below the horizon (green line) than above. The yellow line is the ecliptic. Created using Stellarium and GIMP.

The next greatest elongation of Mercury is the western elongation on April 11, 2019. Here we are looking at it from the southern hemisphere, where it’s autumn displaying its orbit with a transparent horizon at sunrise. Notice how lopsided the orbit appears, extending farther above the horizon (green line) than below. The yellow line is the ecliptic. Created using Stellarium and GIMP.

Note the same is true for both northern and southern hemispheres:

Late winter and spring – planets near and east of the Sun are seen more easily after sunset.

Late summer and autumn – planets near and west of the Sun are seen more easily before sunrise.

02/20/2019 – Ephemeris – Theoretical all 5 bright planets are now visible

February 20, 2019 Comments off

Ephemeris for Wednesday, February 20th. Today the Sun will be up for 10 hours and 42 minutes, setting at 6:18, and it will rise tomorrow at 7:34. The Moon, 1 day past full, will rise at 7:47 this evening.

Let’s look at the planets for this week. We have two evening planets visible now. Tiny and elusive Mercury should be visible low in the west for about a half hour after 7 p.m. It should be visible for a little over a week. Binoculars are a big help in spotting it. Mars will be in the southwestern sky this evening and will set at 11:46 p.m. In the morning sky we have Jupiter which will rise tomorrow at 3:32 a.m. It is second to Venus in brightness. Saturn will be next to rise at 5:22 a.m. It is just to the right of Venus which will rise at 5:29 a.m. tomorrow. In small telescopes Saturn will show its rings and Venus will show a small slightly gibbous moon shape which will shrink and grow more full over the next months
