It seems that Arthur, then living in Workingham, England, had self-published four issues of what he called ''Contributions to Selenography'' mostly featuring measurements he made on copies of glass negatives obtained from Mount Wilson and Lick Observatories. Volume 1 was a list of 1,400 crater diameters measured by J. Young; Volume 2 gave precise positions for 490 features in [[Mare%20Imbrium|Mare Imbrium]]; Volume 3 added 300 features in [[Oceanus%20Procellarum|Oceanus Procellarum]]; Volume 4 gave formulas for converting the X-Y positions observed on a lunar plate to their positions at zero libration; and Volume 5 listed 580 points around [[Copernicus|Copernicus]].

==Lunar Work==<br />
A founding member of the University of Arizona's [/LPL Lunar and Planetary Laboratory], Arthur came to Tucson with [/Gerard%20Kuiper Gerard Kuiper] and [/Ewen%20Whitaker Ewen Whitaker] by way of Yerkes Observatory. At the [/LPL LPL] he oversaw work on the ''[/System%20of%20Lunar%20Craters System of Lunar Craters]'' (a major revision of the [/IAU%20nomenclature IAU nomenclature]) and the [/ULCN Tucson Selenodetic Triangulation] (a new system of positional control points on the Moon). He ended his career with the [/USGS USGS] in Flagstaff where he applied his experience primarily to the analysis of Viking photographs of Mars.<br /> <br /> <br />
==Where & When==<br />
* Before joining Kuiper, Arthur enjoyed some repute as a member of the Lunar Section of the [/BAA BAA]. His activities were highlighted as an example of the kinds of significant work that could be contributed by a dedicated amateur in a 1956 article by ''Sky and Telescope'' editor Joseph [/Ashbrook Ashbrook]. It seems that Arthur, then living in Workingham, England, had self-published four issues of what he called ''Contributions to Selenography'' mostly featuring measurements he made on copies of glass negatives obtained from Mount Wilson and Lick Observatories.
