Widest Full Moon is Not Necessarily the Brightest

Recommended Posts

Several popular science blogs are referring to the Full Moon coming during the morning of 2019 FEB 19 as not only the widest (angular measurement) so-called Super Moon in the current series of three, but also as the brightest Moon of the year. Actually the Full Moon last month was the brightest Moon since 2001 and until 2096. That peak was reached just as it left the Earth’s penumbra following a Lunar Eclipse. I calculated this with use of a Jean Meeus algorithm. For brightness, not only must nearness to the Earth be considered, but also nearness to the Sun and nearness to the anti-solar point. Other sources apparently assume that only nearness to Earth is what matters for brightness.

Here are some results of my calculations:
