A two part reply:
Using the LD I calculated for 18:00:00, 84d 57.8, before any corrections for IC etc. and inputting into the Clearing App I came up with the following:
cos Diff Azm: -01533 I admit I don't know what this tells me, but it is in the report.
Cleared LD: 85d 09.2'
Error in Lunar: 0.3'
Approximate Error in Longitude 9.6' so, I'm not sure how that stacks up as an observation. And it appears to be telling me that GMT at that time was actually 18:05:46. But I also couldn't really tell someone how that could be.... poor shooting? I know it was 18:00:00 and I know the place.
And, more to the point of this whole manual recalculation exercise my LD calc was 84 38.1, Waaayyy off. So, I will start afresh tomorrow and check my work. Plenty of places to screw up decimal places etc. I better get this figured out soon... xyl would like the kitchen table back!
Any suggestions or advice from you, Frank, or anyone else who is reading this saga, would be most welcome.
