Moon Watch: Thunder Moon Eclipse
So...what a Thunder Moon anyway?
A Thunder Moon Eclipse is a penumbral lunar eclipse and it only happens in July. It's name derives from the summer storms that take place around July. It’s also known as the Buck Moon. This is because male deer lose their antlers during this time of year.
The Thunder Moon/Buck Moon (it's whatever you want to call it of the two) will move into Earth’s outer shadow. This creates a penubral eclipse. About a third of the full moon will be covered by the Earth’s shadow, in other words we wont see that part, but it’s for sure worth looking up at moon at just the right time.
