Homework 1

1)         RA:      Midnight at winter solstice, RA = 6 hr

                        4 am at winter solstice +4 hours, RA = 10 hr

                        4 am two weeks after winter solstice +1 hour, RA = 11hr

            Dec:     -90-(-65+(-34))= 9 degrees north

            RA: 11 hr   Dec: 9 degrees N

2)         RA:     Midnight at vernal equinox, RA = 12 hr

                        9 pm at vernal equinox -3 hours, RA = 9 hr

                        9 pm one week before vernal equinox -0.5 hour, RA = 8.5 hr

            Dec:     90-(78)+67= 79 degrees north

RA: 8.5 hr     Dec: 79 degrees N     

3)         RA:     Midnight at winter solstice, RA = 6 hr

                        11 pm at winter solstice -1 hours, RA = 5 hr

                        11 pm one month after winter solstice +2 hour, RA = 7 hr

            Dec:     -(90-24)-48 = -114 = 114 degrees south

RA: 7 hr     Dec:  114 degrees S

4)         244 + 24 - 0.5 + (6/24) + (43/(24*60)) + (36/(24*60*60)) = 267. 78028

Day number: 267.78028

5)         4381.5 + 335 + 21 + (21/(24*60)) + (12/(24*60*60)) = 4737.51472

Day number: 4737.51472
