04/05/2018 – Ephemeris – Hydra, a constellation for all of spring

April 5, 2018 Comments off

Ephemeris for Thursday, April 5th. The Sun will rise at 7:16. It’ll be up for 12 hours and 59 minutes, setting at 8:15. The Moon, 3 days before last quarter, will rise at 1:41 tomorrow morning.

In the southern evening sky can be found the constellation of Hydra the water snake. Unlike the monster of the same name this Hydra has but one head, which is its most distinctive part. At 10 p.m. look to the south. The head of Hydra is located below a line from Gemini and Leo. It is directly below Cancer the crab, and left of the star Procyon. Hydra’s head is a small distinctive group of 6 stars that make a loop and the snake’s slightly drooping head. At that time the sinuous body of Hydra sinks below the horizon in the southeast. As it gets later in the evening the rest of Hydra will wend its way to eventually end beneath Libra the scales. This can also be seen in the next few months as Hydra slithers across the southern horizon.

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