Phases or Eclipse Cycle Observatory?
I haven't read the article posted at http://intarch.ac.uk/journal/issue34/gaffney_toc.html yet, but it seems to me from the illustration posted in the article linked in the main wikipedia page, that rather than observing phases of the moon, this device is better suited to observe lunar latitude, hence eclipses. The lunar nodes precess over a period of about 18.6 years. Eclipses occur when the full moon or new moon correspond to the nodes. I guess it's possible to determine the phases from the lunar latitude if you also know the period in the lunar precession. Victor Engel (talk) 18:41, 15 July 2013 (UTC)
