SIGHT REDUCTIONS

The results above correspond to data found in the Nautical Almanac with an accuracy of   ± 0.1 minute.
Fill in all boxes in the Data Form at left. If you have more than 2 sight reductions, you can calculate a fix by selecting the 2 sight reductions you want to use. All calcuations on this page (and the popups) are based on the data submitted in the form.
