Some clouds are possible Monday night, so Monday morning might be your best chance to gaze at a historic "supermoon."
The moon is technically full at 8:52 a.m. Monday, two and a half hours after the moon makes its closest approach to Earth since 1948. It will nonetheless appear full when it rises at 4:41 p.m. Sunday, just 12 minutes before sunset.
Monday, astronomy group Bmore Popscope will have its telescopes set up outside Penn Station for a close-up view.
This year ends with three consecutive supermoons, and November's Full Beaver Moon is the biggest of them -- and the biggest of this century, so far. On Monday, the moon will swing closer to Earth than it has since 1948.
