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.

03/26/2019 – Ephemeris – Mars is approaching the Pleiades this week

March 26, 2019 Comments off

Ephemeris for Tuesday, March 26th. Today the Sun will be up for 12 hours and 27 minutes, setting at 8:02, and it will rise tomorrow at 7:33. The Moon, 2 days before last quarter, will rise at 2:38 tomorrow morning.

Daylight time and spring time are catching up with us with the Sun setting now just after 8 p.m. By 9 p.m. tonight the brighter stars appear and most of the well known constellations will be recognizable. Looking off to the west at that time the famous star group of the Pleiades, or Seven Sisters will appear. Folks with good eyesight can see six or maybe even seven of its stars. Tonight, right below the Pleiades is a bright reddish star. It would be the 22nd of the first magnitude stars, except it’s not a star. It’s a wanderer, according to the ancient Greeks, one of seven*. They called it Ares the god of war. The Romans turned it into Mars. Over the week Mars will be closing in and passing by the Pleiades this weekend.

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

The letter V of stars to the left of the Pleiades is the Hyades, in mythology the half sisters to the Pleiades.  It is also the face of Taurus the bull.

* We get the word planet from the Greek planētes meaning wander.  Five are the classical planets, Mercury, Venus, Mars, Jupiter, and Saturn.  The other two are the Sun and Moon.  The other celestial objects were the fixed stars.  Other things that appear in the sky, like comets, novae and meteors were thought to be in the Earth’s atmosphere.
