The Super Harvest Moon Eclipse sounds epic — and it is. But the eclipse will be subtle. The Moon will skim part of the perpetual shadow Earth casts behind itself, and only the top four to eight percent of the Moon will be in shadow, according to NASA.

The harvest moon will be a spectacular lunar show in September. Along with a longer viewing period, it'll be a supermoon and partial lunar eclipse.

The moon will appear full for about three days, from Monday evening through Thursday morning, according to NASA.
