TechInsider:

Tonight — Sunday, Sept. 27 — you can see the first “supermoon” total lunar eclipse in 30 years. The moon will turn red, which is normal for a lunar eclipse, but this rare event will be bigger and brighter than those of the past few decades. That’s because the eclipse will coincide with a supermoon — a “very rare” alignment that won’t happen again until 2033.

Check this map to see if you live where the eclipse will be visible. If you don’t live in a visible region, or a big city with too many tall obstructions or a lot of light pollution, bookmark this page.

We won’t see the full effect here on the West Coast but if you’re lucky enough to be able to get outside and see it clearly, don’t miss it. Otherwise, like so many other things nowadays, you can watch online.
