For the first time in 13 years, a full moon will occur this Friday the 13th

For the first time in 13 years, a full moon will occur on Friday the 13th and the next time we'll this phenomenon will be in a little over 13 years, in May 2033. 

This Friday the 13th full moon is the first since January 2006.

But this full moon, most commonly known as the harvest moon, will appear much smaller than most. That's because the moon will be at apogee, or the farthest point in its roughly four-week orbit. Timeanddate.com estimates a "micromoon" appears 14% smaller and 30% dimmer than the widely reported "supermoons" that dominate the news.
