Moon Phase for Saturday Sep 21st, 2024
The current moon phase for September 21st, 2024 is the Waning Gibbous phase.
On this day, the moon is 17.66 days old and 88.46% illuminated with a tilt of -70.581°. The approximate distance from Earth to the moon is 362,404.77 km and the moon sign is Taurus.
The Moon phase for September 21st, 2024 is a Waning Gibbous phase. This is the first phase after the Full Moon where the illumination of the moon decreases each day until it reaches 50% [the Last Quarter phase].
The waning [shrinking] gibbous Moon will rise after sunset in the east, transit the meridian after midnight, before setting after sunrise in the west.
During this phase, the illumination of the moon will go down from 99.% to 50.1%. Technically, the phase starts as soon as the Full Moon has passed, but it can be difficult to calculate and differentiate the first stage of a Waning Gibbous Moon from a Full Moon when 98-99% of the Moon's surface is illuminated.
Fun fact: the word Gibbous was first used in the 14th century and comes from the latin word gibbosus which means humpbacked.

Moon Phases Calendar
For optimal auroral viewing, the Moon may not disturb because light from the Moon can be very bright which causes faint aurora to be barely visible, especially when the chances for auroral viewing are low.
