I thought I'd post a graph of Gregory's lunar listed by George Huxtable, despite the injunction against attachments. The line is a fit of a straight line to the data, which had an R-square of 0.9990. To fit the data on my spread sheet, which knows about hours, minutes and seconds, but not degrees, minutes and seconds, I subtracted 24 degrees from the distance. Also, since George had bragged about the data being so good, I assume that his data point at 22h 39m 00s 29d 43' 50" was a typo, where the 43' should have been 45', and changed that point accordingly. To all us nascent lunarians, when our data on land look like these, we should be as ready as we can be for sea! Fred
