You can also tell me the answer. I want the azimuth of the moon anytime between February 17, 2007 - February 28 2007.

I need at least two days.

Well it's kind of cloudy here in Seattle and is going to stay this way for at least a week...

I found this one, even though it is not as user-friendly as a planetarium program, it still allows you to enter your position (lat and long.).

If you need azimuth to the nearest degree, then your lat. and long. to the nearest 0.5 degree is sufficient.

They even allow you to use a list of cities. Seattle WA is there.

At first shot, it gives you a sky map for "now"

Scroll down to see the altitude and azimuth of the planets and the Moon. A negative altitude means that it is below the horizon.

Scroll back up, change the time (and date, if you want) and click on update. Make sure that you keep the same format as they use for date and time (yyyy-mm-dd hh:mm:ss) in universal time. Seattle, WA, is 8 hours behind, so for 5 a.m. your local time it is already 13:00:00 in universal time (same date). For 7 p.m., it is already 3:00:00 UT next day.

Repeat as often as necessary.

PS: Another annoyance:
Azimuth is given as an angle from the South. They claim that this follows the "astronomical convention". I've never heard of this convention.

In any event, if you want to convert to nautical azimuth Z (North = 000, East = 090, South= 180 and W=270), then do:

Z = 180 + F, where F is the azimuth given by fourmilab.

So that if F = -100, then Z = 180 +(-100) = 80 (ten degrees north of East).

Enjoy

Why would you need that, it's visible in the sky!

The only things you'll generally find are RA and DEC (right ascentiaon and declination) because Azimuth is a relative term.
