An interesting questions posed on a local bay area sailing group. I will relay the answer back to Max Guy From: SanFranciscoSailing@yahoogroups.com [mailto:SanFranciscoSailing@yahoogroups.com] On Behalf Of maxjosefspring Sent: Sunday, February 22, 2009 12:13 AM To: SanFranciscoSailing@yahoogroups.com Subject: [San Francisco Sailing] reusing old nautical almanacs I wonder whether it would be possible to re-use an out-dated nautical almanac for celnav purpose by determining the "error" through an accurate measurement. It appears to me that might work fine for the sun and stars, but probably not for the moon and the planets. Has someone maybe even done this? -Max __._,_.___
