Hi Paul, I'm just going through exactly the same process - it's pretty exciting. First I did a couple of lunar distances. Then I worked out that a bucket of water on "the bridge" - the deck outside my upstairs bedroom - made a great artificial horizon. I got a series of afternoon position lines - intercepts of 2.7m, 0.7m and (gulp) 5.7m. The wind had started to blow and the sun in the bucket wouldn't stay still! For various reasons I haven't been able to do a noon sight and today being the Melbourne Cup holiday here I thought I'd do one. To get a true northerly horizon I'd have to drive for a couple of hours so it's back to the bucket on "the bridge". Then I looked at the data for my DR: LAN at 13:03:34 - so far so good and Hc 66d 17.4m - the bucket doesn't do it. My sextant only measures 120d and because of the double reflection issue won't measure the required altitude. So unfortunately the meridian passage sight will have to wait. It's pretty exciting though. Best wishes Mike --- Paul Flintwrote: > If you have socks to wash or anything even mildly > interesting to do, > skip this message. > > A landmark event occured today.
