01/01/2019 – Ephemeris – Previewing the month of January 2019

January 1, 2019 Comments off

Ephemeris for New Years Day, Tuesday, January 1st. The Sun will rise at 8:20. It’ll be up for 8 hours and 52 minutes, setting at 5:12. The Moon, 3 days past last quarter, will rise at 4:59 tomorrow morning. | Happy New Year. Let’s preview the month of January. We’re a day from the latest sunrise at about the same time as today, 8:20 a.m. and will back down to 8:03 by the 31st. Sunset times are currently increasing by a minute a day from 5:12 p.m. today to 5:49 at month’s end. Listeners will have about the same sunrise time in Ludington, Interlochen/Traverse City, Petoskey and Mackinaw City, but the sunset times will vary markedly with the sunset times earlier in the north than the south. The Quadrantid meteor shower will reach peak on the 3rd in the evening. Also on the 3rd the Earth will be its closest to the Sun for the entire year. And on the 20th there will be a total lunar eclipse in the evening.

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

The planets and stars are plotted for the 15th at 9 p.m. EST in the evening and 6 a.m. for the morning chart. These are the chart times. Note that Traverse City is located approximately 45 minutes behind our time meridian. (An hour 45 minutes behind our daylight saving time meridian during EDT). To duplicate the star positions on a planisphere you may have to set it to 1 hour 45 minutes earlier than the current time.

Note the chart times of 9 p.m. and 6 a.m. are for the 15th. For each week before the 15th add ½ hour (28 minutes if you’re picky). For each week after the 15th subtract ½ hour. The planet positions are updated each Wednesday on this blog. For planet positions on dates other than the 15th, check the Wednesday planet posts on this blog.
