Friday is the longest day of the year. (OK, technically, the longest day started on Thursday night.) But no need to feel all deflated once it’s over: you still have the supermoon to look forward to. That’s when the full moon is especially close to the Earth. And it’s coming this weekend.

EarthSky explains astronomers call this a perigee full moon, which, granted, sounds less dramatic. Whatever you want to call it, it will be full, and it will be close. has more details.

Supermoon Rises in Weekend Night Sky SundaySunday’s lunar perigee will be the moon’s closest to Earth of 2013. And 32 minutes later, the moon will officially turn full.

But still — in case you need one — it seems like a good enough excuse to get outside Sunday night and look up.
