Supermoon Saturday has arrived -- now get ready to look up for some "super" skywatching.
The full moon at 11:34 p.m. EDT Saturday will appear 14 percent bigger and 30 percent brighter than normal as it approaches slightly closer to Earth in its orbit, reaching perigee, according to NASA. The moon then will line up with the sun just one minute later.
"It is called a supermoon because this is a very noticeable alignment," Dr. James Garvin, chief scientist at NASA's Goddard Space Flight Center, said in a statement accompanying a new video on the topic. "The 'super' in supermoon is really just the appearance of being closer."
