Letronne Crater - 24 June 2018

Letronne is a 120km (72 mile) diameter lava-flooded remnant of a lunar impact crater. The northern part of the rim is completely missing, and opens into the Oceanus Procellarum, forming a bay along the southwestern shore. The formation is located to the northwest of the large crater Gassendi.To the west-southwest is the flooded crater Billy, and north-northwest lies the smaller Flamsteed.

The surviving rim of Letronne is now little more than a semi-circular series of ridges. The flooded, broken rim of Winthrop overlies the western wall. The rim is the most intact along the eastern stretch, forming a mountainous promontory into the mare. A small cluster of central rises lie at the midpoint of the crater. An 8km wide wrinkle ridge known as Dorsa Rubey traverses the floor from north to south for aproximately 100km. The crater floor is otherwise nearly smooth and relatively free of craterlets, with the exception of crater Letronne B (5km diameter) near the southeast rim.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
