When the moon's orbit crosses the shadow of the Earth, an interesting phenomenon happens. We call it a Lunar Eclipse, and when it happens, the moon takes on a reddish hue. It's a twice-yearly event, but this time around, it coincides with a Super Moon. In case you're unaware, a Super Moon happens when the moon is at its closest point to Earth. Given the moon's elliptical (rather than circular) orbit, it's a full 14% closer (and larger) at this point than it is on average.
This coincidence is a rare event. Just to give you some perspective, this coincidence has only happened five times since 1900, and it won't happen again until 2033. Unless you're willing to wait 18 years to see it, you better be prepared at the end of September, because this is happening whether you're ready or not!
For the best viewing experience, make sure you're somewhere with a clear view of the sky!
