This article describes the recorded phenomena in detail and presents new evidence on the astronomical orientation of the temple. The second section puts forth a possible methodology for the architectural layout and design of the Temple of the Sun. The geometric proportions and angles of the temple appear to correspond with the astronomical alignments of the temple.
