As if "supermoon" isn't cool enough, the technical term for the moon when it's closest to the Earth is: perigee-syzygy.
It happens about once a year, and this year it fell on June 23, though the day prior wasn't bad, either. According to NASA, this year's supermoon was "14% larger and 30% brighter than a typical full moon."
It's not easy to photograph with a smartphone, but that's what photographers with nice lenses are for.
