Question for you Physics/Astronomy people!

I forgot to include the second part of your question this is really easy:

Local Hour Angle (LHA) for Capella:

LHACapella = LSTAbbotsford - RACapella (If the result is negative add 360, if the result is greater than 360 subtract 360)

We can just use our LST degree calculation: 345.98290934 degrees

Next we need to find what the (R.A. 5h 16m 41.5s) translates into degrees

so we just do the last step of our last calculation backwards:

[(41.5 X 360/24) /60] /60 = 0.17291666

(16 X 360/24) / 60 = 4

5 X 360/24= 75

Add all those results together and

Aur RACapella = 79.017291666 degrees

So,

LHACapella = 345.98290934 - 79.017291666 = 266.96517674 degrees

I got most of what you said except this one part:

Greenwich Sidereal Time (In Degrees) is found as follows:

GST = (Sidereal Time on Jan 1st 2000 in degrees) + (#of Sidereal Degrees/day) (Number of Days)

GST = (280.461)+(360.98564737)(5014.79176) = 1810548.3109093416

Next from that number we want to eliminate multiples of 360

Which leaves us with:

108.31090934

How did you get that number? Or what was the equation rather.

I'm so sorry the Julian Day I gave was Incorrect (It was 1 day more I calculated for Sept. 23, 2013 instead of Sept. 22)

it should be 2456558.79167 or 5013.79167 days from J2000 (Jan 1st, 2000 noon GMT)

So you can plug that into the equations and you should end up with

22:55:55 approximately as your final answer for the Local Sidereal Time

which would also change the LHA for Capella

You just keep subtracting multiples of 360 until you are between 0 and 360. Or Adding if you go too far.

I knew you made a mistake.
