04/05/2017 – Ephemeris – It’s Wednesday, do you know where your bright planets are?
Ephemeris for Wednesday, April 5th. The Sun will rise at 7:15. It’ll be up for 12 hours and 59 minutes, setting at 8:15. The Moon, 2 days past first quarter, will set at 5:04 tomorrow morning.
In the evening twilit sky tonight will feature the elusive planet Mercury. This tiny planet might be seen to the upper right of the Sun’s setting point starting about 9 p.m. It will set at 9:55 p.m. Mercury is getting rapidly fainter because it’s now exhibiting a diminishing crescent to us. It takes a good telescope and very steady skies to spot Mercury’s phase. Mars is still hanging on, in the west above and left of Mercury, and will set at 11:09 p.m. Jupiter will rise about sunset a half hour before the star Spica, which it will be seen to hang out with this year. Jupiter will be still seen in the morning sky low in the southwest at 6 a.m. Saturn then is in the south above the Teapot figure of Sagittarius. It will rise at 2:06 a.m. in the east-southeast.
Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

A comet dramatically brightens

Here is the track for Comet 2017 E4 Lovejoy. This comet was expected to be 14th magnitude, but it’s brightness shot up to around 6.5, within range of binoculars. I’m only plotting 10 days. It should be brightest about mid-month, but is poorly placed for observation, plus we’re fighting a bright Moon. The curved horizontal line near the bottom is the Horizon on April 4, 2017. Created using Cartes du Ciel.

03/29/2017 – Ephemeris – It’s Wednesday, do you know where your bright planets are?
Ephemeris for Wednesday, March 29th. The Sun will rise at 7:28. It’ll be up for 12 hours and 38 minutes, setting at 8:06. The Moon, 2 days past new, will set at 10:10 this evening.
In the evening sky tonight, replacing Venus will be the elusive planet Mercury. This tiny planet might be seen to the upper right of the Sun’s setting point starting about 9 p.m. It will set at 9:49 p.m. Mars is still hanging on, in the west, and will set at 11:10 p.m. The thin sliver of a crescent Moon is seen left of and above Mercury and Below Mars tonight. This might be a good time to spot Earth shine on it’s night side. Jupiter will rise in the east at 8:47 p.m. a half hour before the star Spica, which it will be seen to hang out with this year. Jupiter will be still seen in the morning sky low in the southwest at 6 a.m. Saturn at the same time is in the south above the Teapot figure of Sagittarius. It will rise tomorrow at 2:33 a.m. in the east-southeast.

03/22/2017 – Ephemeris – Wednesday is bright planet day but we seem to be missing one of them
Ephemeris for Wednesday, March 22nd. The Sun will rise at 7:41. It’ll be up for 12 hours and 16 minutes, setting at 7:57. The Moon, 2 days past last quarter, will rise at 5:09 tomorrow morning.

It will rise tonight at 9:19 p.m. in the East. Saturn can be glimpsed this morning above the Teapot figure of Sagittarius in the south. It will rise tomorrow at 3 a.m. in the east-southeast. The crescent Moon will be in the east-southeast. In the evening sky tonight Venus is essentially gone, just 3 days from passing inferior conjunction, it might be seen to the upper right of the Sun’s setting point. I once spotted it this close to conjunction in the bright twilight. It will set at 8:35 p.m. Mars is still hanging on, in the west, and will set at 11:11 p.m.

In Memorium
Yesterday we lost the 11th man to set foot on the Moon and the last one to leave it. Eugene Cernan, the commander of Apollo 17 hated the title of “The last man to walk on the Moon”, and hoped before he died that another would walk on the Moon, lifting that title from his shoulders. Of the 12 men who walked on the Moon, half are now gone. The way things are going the next person to walk on the Moon will probably be Chinese. Godspeed Eugene Cernan.

It will set at 9:03 p.m. Later this month Mercury and Jupiter will pass the Sun to become visible in the morning sky. Venus alone will remain in the evening sky, slowly pulling away from the Sun. Mars, Saturn and the star Antares start the evening in the southwestern sky in a triangle, with Saturn on top, Mars below and to the left, and Antares below and right of Mars. Saturn, spectacular in telescopes with its rings, will set at 11:45 p.m. And Mars, moving rapidly to the east against the stars will set at 11:50 p.m.
