07/23/2019 – Ephemeris – Finding Cygnus the swan in the stars

July 23, 2019

Ephemeris for Tuesday, July 23rd. Today the Sun will be up for 14 hours and 59 minutes, setting at 9:18, and it will rise tomorrow at 6:20. The Moon, 1 day before last quarter, will rise at 12:50 tomorrow morning.

High in the east at 11 p.m. Is the constellation of Cygnus the swan, flying south through the Milky Way. It is also called the Northern Cross. At the left, the tail of the swan or the head of the cross is the bright star Deneb, one of the stars of the Summer Triangle. The next star right is Sadr the intersection of the body and the wings of the swan seen in flight, or the intersection of the two pieces of the cross. There are two or three stars farther to the right that delineate the swan’s long neck or upright of the cross, that ends with the star Alberio in the beak of the swan or foot of the cross. The wings of the swan span a couple of more stars on each side than the crosspiece of the cross.

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