Full sturgeon moon on Thurs.

My understanding is that it is more about being brighter than being larger. It tricks the brain into thinking it's larger. Likewise, it's an optical illusion that the sun or moon looks larger at sunrise/moonrise and sunset/moonset.

What's interesting is although it's easy to prove it's an optical illusion, they don't completely understand why our brains see it that way.

The sun and moon look larger due to moisture in the atmosphere magnifying them when they are low on the horizon.

If that were the case, pictures of the moon taken when very low on the horizon would be measurably larger than those taken at a higher azimuth. The NASA article mentioned states that is not the case.

Sturgeon moon??? Sounds fishy to me! Oh, I can hear the groans now...

Well, that's where it got it's name. Tribes around the great lakes called it that as they could more easily catch these large fish during the full moon in August.
