    HELP.....The Azimuth and Altitude of Star Vega

    What is the azimuth and altitude of the star vega because i am not sure I got the right star so could anyone help me?


    over the course of three days does the Azimuth and Altitude stay the same of is it different and why?

    Secondly.... What about if you were to observe the same star at the same time of day three
    months from now? Where do you think it would be with respect to where it is
    now? Briefly explain your reasoning.

    The azimuth and altitude of a star vary minute-minute, that's why we use right ascension and declination. The declination of a star is fixed.
    You will also need to understand local sidereal time - wiki has good articles.

    The second part sounds like a homework question

    Confused: you are asking for a particular star position for at least the second time. There are plenty of programs in which you enter your geographical position, time, and they show sky maps. Just google them or visit tucows or something. Just try. It is 15 minutes effort.
