This is it.

The biggest supermoon since 1948 will light up the night's sky on November 13 and 14.

If you miss it, your next chance to see the moon this big will be November 25—in 2034. In other words, make some time to look up on Sunday or Monday.

The term “supermoon” signifies a new or full moon that is within 90 percent of its closest approach to Earth, meaning it's the closest it gets as it circles this planet of ours.

To make the most of this moon, which could appear up to 14 percent larger and 30 percent brighter than usual depending on where you are, head to somewhere dark (away from urban light pollution) and also consider what kind of foreground objects could offer perspective.

“When the moon is near the horizon, it can look unnaturally large when viewed through trees, buildings, or other foreground objects,” according to NASA. “The effect is an optical illusion, but that fact doesn’t take away from the experience.”
