Fred, > Do you notice any correlation of good/bad > lunars with the orientation > of the sextant? Not really, though it is hard to tell. The conditions rarely repeat. What makes it really strange is that the error when present is usually constant in long series. So averaging does not help. I would almost say that it is constant during a day... though this is not always so. It looks like it depends on... weather:-) Thopugh I understand that this idea is absurd. Some new kind of strong abnormal refraction in Indiana? > That also is > suggested by the side error wandering around. According to a formula in Chauvenet, the side error of less than 1' has completely negligible effect at all angles.
