Sunrise at Deslandres

Each new low image of the Sun reveals more aspects of the lunar surface. The exquisite view I got from this photo of the strange Deslandres crater is no exception. It reveals the ruggedness of the topography on a scale of about 600m, small craters and hills overlook the landscape, but these are just the latest of the features deposited there.

Deslandres - formerly and informally called Hellplain - is a fascinating but often overlooked lunar crater. With a diameter of 227 km (slightly larger than Clavius with 225 km), it is one of the largest craters on the nearby side.

With this diameter Deslandres must have originally had 5-6 km of depth, but is now only about 1 mile. In order to have this great amount of filler probably the greatest contributions were deposits of the formation of the Humorum Basin, with some also ejected from Imbrium and Orientale.

This image with the extremely low sun shows some disconcerting characteristics. My friend Chuck Wood says he can see pieces of what would be an inner ring with a gross diameter of 70 km and still ask: Is Deslandres a two-ring impact bowl like Compton?

If so, the inner ring is rather small - usually the inner ring bowl is about 50% of the diameter of the main ring - or 110 km to Deslandres.

One can also see running to the right side of the yellow arrow a wide rille type trough about 110 km long and 10 km wide. It is very unusual for a rille to develop on rough terrain like this.

Anyway, an intriguing image with many amazing aspects, just know how to look!

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.
