But will we be able to tell the difference ... just by looking? A 30% difference in brightness can easily be masked by clouds or the glare of urban lights. Also, there are no rulers floating in the sky to measure lunar diameters. Hanging high overhead with no reference points to provide a sense of scale, one full Moon looks much like any other.
"I think that the hype over the term 'supermoon' is a bit overblown," says Chester. "In my book every full Moon has something to offer!"
To get the most out of Monday's apparition, try to catch the Moon just as it is rising or setting. This will activate the Moon Illusion and make the perigee Moon of Nov. 14th look super, indeed.
