The first ‘supermoon’ lunar eclipse in over 30 years will grace our skies later this month.

Depending on weather conditions on September 28, lucky viewers will see a full moon that looks larger and brighter than usual, with a red tinge.

It will be first ‘supermoon’ lunar eclipse since 1982 and there won’t be another until 2033, according to Nasa.

Friday will see 3 rare celestial events: Solar eclipse, Supermoon, Spring equinox

Supermoon

It’s a Total Solar Eclipse in the Faroe Islands and Svalbard (Norway), and a Partial Solar Eclipse in Europe, northern and eastern Asia and northern and western Africa. The eclipse starts at 07:41 UTC and ends at 11:50 UTC.

As the eclipse plunges these places into darkness this Friday, two other rare if less spectacular celestial events will be taking place, too: a Supermoon and the Spring equinox.

A Supermoon, or perigee moon, happens when the full or new moon does its closest fly-by of the Earth, making it look bigger than it normally does. And the spring equinox refers to the time of the year when the day and night are of equal duration, mid-way between the longest and shortest days.

The solar eclipse refers to a phenomenon where the sun and moon line up, so that the latter obscures the former. And while it won’t be affected by the two other events, it is rare that the three events happen even individually.

You’ve heard of the supermoon. Get ready for the opposite–a mini Moon

The full Moon of March 5th will be as much as 50,000 km farther away than other full Moons of the year, making it smaller and dimmer than usual. 

The apparent size of the Full Moon changes throughout the year because the Moon’s orbit is not a circle, it is an ellipse, with one side (apogee) 50,000 km farther from Earth than the other side (perigee): diagram. When the Moon is on the apogee side, it looks smaller and dimmer in proportion to its increased distance.

Can you tell the difference? Some people say “yes,” others “no.” There are no rulers floating in the sky to measure lunar diameters. Without a reference, it can be challenging to distinguish an apogee Moon from a perigee Moon. Decide for yourself. Go outside after sunset on March 5th, look east, and enjoy the mini-moonlight.
