Domes are one of the most intriguing types of landforms on the Moon. Their elevations are so low that they can only be glimpsed or imaged when the Sun is only a few degrees above the surface. And domes are commonly less than 10 kilometers in diameter so that seeing any detail on them is difficult. But perhaps the most challenging aspect of dome studies is deciding if a particular object is an already known dome. The problem is that many different observers have described domes and suspected domes, but have had inadequate maps to determine accurate positions.
Currently two researchers,Robert A. Garfinkle, F.R.A.S., and Charles Kapral, are systematically examining all domes listed in previous ALPO (1992) and BAA dome catalogs, other publications, and from their own observations and research to determine the reality and nature of each reported dome. They are also trying to re-determine dome coordinates using a consistent coordinate system. Although each of their catalogs is still in preparation, Garfinkle and Kapral have allowed Brendan Shaw to plot the domes on the 1960s era Lunar Aeronautical Charts and further have agreed for Shaws LAC charts be presented here so that other dome researchers can quickly and visually check if a particular dome has been previously reported. Currently only a domes position and approximate diameter are indicated on Shaws charts; in the future it would be ideal if any dome circle on the LAC maps could be clicked on to open a window describing that specific dome.
The maps (only LAC 61 is currently available) show circles in the locations of domes listed in the revised catalogs of Garfinkleand Kapral. Red circles are domes that appear in bothcatalogs and whose positions agree within 0.1 degree, Green domes appear only in Kaprals catalog and blue ones only in Garfinkles catalog.

Thanks to Brendan, Bob and Charlie for their hard workmaking prior dome compilations more reliable and more useable by all! And to theGeologic Lunar Researchgroup that these three are coordinating with!
