Contrasting an average-size full moon with a large full moon

The July 2011 full moon will fall on Friday, July 15 at 6:40 Universal Time (UTC). Although the full moon comes at the same instant for everyone worldwide, the clock – as always – reads differently according to time zone. In the United States, the full moon occurs on July 15 at 2:40 a.m. Eastern Daylight Time, 1:40 a.m. Central Daylight Time, 12:40 a.m. Mountain Daylight Time and 11:40 p.m. (on July 14) Pacific Daylight Time. Can you see how the moon will appear more full on the night of July 14 than on the night of July 15 for us in the United States?
