REPORT ON THE ALPO LTP OBSERVING PROGRAM

摘要

The main objectives for the program are:(1) to monitor LTP sites and non-LTP comparison sites for normal as well as abnormal aspects in a random night observing format;( to establish quantitative albedo scales for each feature for each sunlit day (to decrease or eliminate the waxing phase bias of historic observations);(3) to establish a quantitative seeing scale based on the behavior of a star's diffraction disk. The first step for the observer was to set up his own albedo scale by observing at full moon and to produce a gray scale based on Elger's gray scale, with either pencil shadings or exposed film or paper.
