Here are some comments on Georges recent posting: I am avoiding apostrophes as they come out scrambled. 1. I believe that the program Redshift was originally developed by space boffins in the USSR. It agrees, give or take a few seconds, with Georges moon transit predictions. 2. The moons meridian passage at London on 9th July 1612 that I quoted is in apparent time and based on the meridian of London. Interestingly, the first map ever published with this meridian is of Hertford where I live) 3. David Origamus was the author of an ephemeris for the years 1595 until 1650 and based on the meridian at Wittenberg. Later in his journal, Baffin uses both Origamus and Searle with similar results and refers to a 17 degrees difference in longitude between London and Wittenberg. 4 Unfortunately, the error regarding latitude was mine not Baffins! 5. Baffin generally used a 4 feet semi-diameter quadrant to measure the suns altitude. Tony C
