I found the beginning of this trend on October 10. Am I missing something?" Yes. See January. Or... go through any of my posts in the past nine months referencing "dip" and/or "Chicago buildings" in the subject. The calculation of anomalous dip is directly connected with terrestrial refraction which, to first order, is a simple function of the atmospheric lapse rate. It's fun stuff, and I would be happy to chat about it at some length (you can express everything in terms of a variable radius for the Earth!), but unfortunately I am very busy this weekend. Strike that... make it "FORTUNATELY I am very busy this weekend". -FER 42.0N 87.7W, or 41.4N 72.1W. www.HistoricalAtlas.com/lunars
