[net.astro] Right Ascension Determination

dimario@ihlpg.UUCP (Michael J. DiMario) (08/22/85)

I am looking for a clear explanation of determining the R.A. of an
object given its R.A. at 0h UT for a given meridian. I seem to
have difficulties w/ this in the field. For example, given that Jupiter
is at R.A. 20 53.0 on Aug 16th at 0h UT, what is its R.A. at 88 degrees
W. longitude? Is this the Hour Angle and if so, how do you use it?

Thank you in advance.
