"The moon in June is a big balloon." Yes, it is September and that saying doesn't really make sense right now, but it will. The moon has a lot going on Tuesday night.
For starters, the moon has entered its full phase in the 28 day lunar cycle, which peaks tonight and will appear full through Thursday morning. Since this is September's full moon, the closest to the beginning of the fall season, it's also known as the harvest moon, which is a signal to farmers that the end of the season is near for summer crops and to prepare the harvest.
The second thing happening is the supermoon as it is at its closest point to the earth in its orbit which will happen at around 9:35 pm. At that time it will appear just a bit larger.
Lastly (as if that's not enough) the moon will briefly be passing through the Earth's shadow creating a partial eclipse. You won't have to stay up too late to view all of this as the eclipse will begin around 9:13 pm and the moon will remain within Earth's shadow for about an hour, with its peak at around 9:44 pm. As it's not a total eclipse, the light won't be completely blocked but you'll likely see that reddish tint to the moon, making this harvest supermoon a blood moon.
In contrast to the total solar eclipse we experienced in April, this is a lunar eclipse, so no special equipment is needed to view it.
So pull out your lawn chairs, sit back and enjoy the full super harvest moon with bonus partial lunar eclipse!
