Attached are the completed reductions for observations using the civil twilight precalculations to preset a Navy MK V bubble octant. All LOPs were within 2' NM of the actual position. For a bubble octant this is very good. Conditions were ideal. The Polaris observation was the toughest. A mistake was made on the original Polaris precalculation. 25' should have been subtracted from the assumed latitude for a 33° 45' preset. Polaris was still in the field of view even with the error.
