Measure of elevation of Antares at 30minute intervals

  1. Oct 16, 2007 #1
    please help!!

    I need to know the measure of elevation of Antares at 30minute intervals from 7pm to 10.30pm.

    It's for an assignment and I don't have any idea how to do it. =(

    Any help at all would be very very very much appreciated.

    buy a sextant, sit outside, find antares, measure its elevation every half hour, starting at 7pm...

    You could also look up the declination of antares, and your own lattitude and longitude. Then convert declination to altitude. You can look up the conversion online, there are various methods. You'll need to do the conversion for each time listed.

    My guess would be that your teacher will want to see the math, so you'll have to do this yourself (with a method probably like what Gale suggested).

    You'll need the date too...
