AST 1001 Chapter Notes -Hour Angle
Document Summary
This is easily done by standing in the mall area and facing coffman: date: day and month observation are taken, clock time: standard am/pm time of observation, decimal cst: means military time. Ex: 9:45 am = 9. 75 in decimal cst. 6:15 pm = 18. 25 in decimal cst: sun"s ha: sun travels about 15 across the sky in an hour. So at noon, when sun is directly over head, it"s hour angle is 0. Every hour after /before noon adds/subtracts 15 to the hour angle. The equation to calculate the sun"s ha is: We will measure the moon"s position as its angle from the meridian, by sticking your arm out straight and counting the number of side-by- side fists it takes to reach the moon from the meridian. West of meridian = (+) : moon ha: this value is calculated from your observed number of fists and your degrees/fist value, which you will calculate in lab.
