These photos compare the super-moon to the moon one and two days away from perigee.
Then I centered and top-aligned my circles:
The thicker line at the bottom shows the difference in size between this super moon occurring near perigee and other super-moons occurring a day or two from perigee. This difference is barely detectable with my method.
So, if you missed the May 5 super-moon, you didn't miss anything other than the novelty of the timing of full moon and perigee being 1 minute apart.
