Description
Dubyago is one of a number of mare lava flooded craters that are part of Mare Undarum. This area is like a miniature Mare Australe and makes me wonder if there is an ancient undetected basin there. Dubyago's central peak is completely invisible (covered by lava?) and the terraces are largely smoothed out. The Orbiter image suggests that the crater on the floor of Dubyago may be a concentric crater - it seems to have an inner ring, but it looks flooded too. - tychocrater Jun 30, 2007

Additional Information
- Depth data from Kurt Fisher database
- Westfall, 2000: 2.7 km
- Nearby concentric crater, immediately southwest of Dubyago. Note that there's another Concentric Crater south of nearby crater Liouville.
Nomenclature
- The current IAU name honors two men:
- Dmitry Ivanovich Dubyago (September 21, 1849 - October 22, 1918), a Russian astronomer and expert in theoretical astrophysics, astrometry, and gravimetry.
- Alexander Dmitriyevich Dubyago (December 5, 1903, Kazan - October 29, 1959), a Soviet astronomer and expert in theoretical astrophysics.
- The name Neper A (Schubert A to Julius Schmidt) was Catalog Number 7 in Mary Blagg's Collated List and in the original IAU nomenclature of Named Lunar Formations (1935), where the designation is attributed to Beer and Mädler.
- The replacement name Dubiago was proposed by Arthur and Whitaker in the Rectified Lunar Atlas (1963) and approved by the IAU in 1964, with the biographical information published in Menzel, 1971.
- The spelling was changed to Dubyago at an unknown later date.
