Answer to Question 1

A waxing crescent moon cannot be observed on the overhead meridian at 10 A.M.
local time but can be seen on the overhead meridian at 4 P.M. The waxing crescent
moon begins as the new moon ends (12 noon local solar time), continues for 7 3/8
days, and ends at the time of the first-quarter phase of the moon. Because the new
moon occurs at 12 noon local solar time, and the first quarter at 6 P.M., the waxing
crescent can be seen on the overhead meridian between these two times.
