55.37 N is the result of latitude calculation.
You need to know which hemispehere you are on before this calculation (to decide if you will be adding, or subtracting and how )
How do you now initially you haven't cross equator if you are completely lost?

Sorry but if i would have to use some excel, i would rather turn my realism to show my position itself, i would like to use only almanac or whatever else what was available at 1939 u-boat
How to get LHA from Almanac? I want to find even longitude for myself, that Excel needs to calculate it somehow, but i haven't found how

Maybe i can ask even another way:
1) Are we able to get longitude in another time, than when the sun is at highest position? (I expect no)
2) Can i get longitude by knowledge which GMT time is the sun at highest position? I expect so, because it should be something like +15 degrees E for every hour after 12:00AM or +15 degrees W for every hours before 12:00AM minus GHA

Thank you for quick response!
