Discussion Overview

The discussion revolves around how to measure the elevation of the star Antares at 30-minute intervals between 7 PM and 10:30 PM. It is framed as a homework-related inquiry, seeking assistance with the methodology and calculations involved.

Discussion Character

  • Homework-related, Exploratory

Main Points Raised

  • One participant requests help for an assignment involving the measurement of Antares' elevation.
  • Another participant suggests using a sextant to measure the elevation directly at specified intervals.
  • A different participant proposes looking up the declination of Antares along with the observer's latitude and longitude to convert declination to altitude, indicating that various online methods exist for this conversion.
  • One participant speculates that the assignment will require showing the mathematical work involved in the calculations, implying that the date of observation is also necessary for accurate results.

Areas of Agreement / Disagreement

Participants present different methods for measuring elevation, with no consensus on a single approach. The discussion remains unresolved regarding the best method to use.

Contextual Notes

Limitations include the need for specific date information and the potential complexity of the conversion methods mentioned, which may vary.

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...
