Order of Ascension
The following tables list the constellations in order of Right Ascension... or the Local Sidereal Time and order in which they will appear exactly on your local meridian. Use this with your Local Sidereal Clock to determine what is currently rising, what is on your meridian, and what is setting. For example: Orion has an RA of about 5h 34m. So when your local sidereal clock displays 05:34:00, Orion is directly on your North/South Line. Of course depending on the time of year, it might also be 9:00 AM Local Solar Time and you can't see any stars; or depending on your local latitude, Orion may be below the horizon.
