The Moon at Night

The past several nights have had mild weather, so I opened the bedroom window and set the blind so air could pass through. This gave me a view of the eastern sky over my neighbor's house as I lay in bed each night.  My erratic sleeping habits had me glancing through the blind. The first couple days, the nearly full Moon sent light pouring into the room, but each day the waning Moon grew thinner and reached the sweet spot later. How many astronomy professors have given how many students an observing assignment like this?
