Werner D's high-albedo ejectablanket
A fine test object for every kind of telescope is the small crater at the centre of the high-albedo ejectablanket on the northern part of Werner's rim (officially known as Werner D). Are there possible changes in the brightness of that ejectablanket? (several dedicated moonobservers of the past compared it with "similar" changes of brightness at other high-albedo spots such as Lassell D, Linné, and Posidonius Gamma).

The hook-shaped tracks of the boulders in Werner D's ejectablanket
It's interesting to explore the LRO's NAC close-ups of the ejectablanket around Werner D. The location of the bright crater Werner D is on the northern inner slope of Werner itself. The tracks of almost each one of the ejected boulders (from Werner D) look remarkably "hook-shaped", because they rolled down the slope, southward.

Nomenclature
- Johannes Werner (February 14, 1468 – May 1522) was a German mathematician. His primary work was in astronomy, mathematics, and geography, although he was also considered a skilled manufacturer of instruments. Many consider Werner as a pioneer of modern meteorology and weather forecasting. Between 1513 and 1520, Johann Werner made the first regular observations of the weather conditions in Germany.
- Werner Alpha (the central peak of Werner) (see Chart 83 in the Times Atlas of the Moon).
