About the labels and credits
Feature positions and the latitude/longitude grid are projected from a verified lunar solution by SkySolver, by Dominik Sito. The original photograph is unchanged. Feature names and coordinates follow the IAU Gazetteer of Planetary Nomenclature (USGS). Some crater centres lie in shadow.
The Montes Jura line follows the approximate USGS catalogue extent. It does not trace every mountain peak or the changing edge of the Golden Handle illumination.

Overview
The Golden Handle is a feature on the Moon that’s visible once a month. When the angle of the Sun is just right, it catches the peak of a mountain range called Montes Jura, lighting it up like a giant letter “C”.
Background
I had a fun time imaging the Moon, resulting in my Lunar X and Lunar V photo, so decided to have a crack at the Golden Handle, another feature that you need to get the timing just right to see.

Science
The distinctive Golden Handle “C” shape is light skimming across Montes Jura. This is the surviving portion of the rim of the ancient impact basin, which explains why it’s so curved; it’s essentially part of a circle. The Golden Handle is visible for a few hours when the Moon is waxing, around 10 to 11 days after New Moon. The effect is caused entirely by perspective and the low angle of the rising Sun. So, like the Lunar X and V, the Golden Handle is an optical effect rather than an actual physical feature.
Inside the arc of Montes Jura lies Sinus Iridum, Latin for “Bay of Rainbows”. The bay occupies an ancient impact crater roughly 240 kilometres across. The impact formed the crater and its raised rim, of which Montes Jura is the surviving mountain arc. Later, basaltic lava flooded the interior and buried part of the rim, creating the relatively smooth plain we see today. The crater and its lava-covered floor therefore formed at different stages of lunar history.
