The moon was observed Tuesday morning at sun rise. The angular distance was 65 degrees. Wednesday morning the reading was 53 degrees. The moon is approaching the sun at the rate of about 12 degrees per day.
Thursday morning it will be 41 degrees, Friday morning 29 degrees, Saturday morning 17 degrees and Sunday morning 5degrees which means the waning crescent will not be visible on Sunday morning.
