    NASR question on large F values
    From: John Pinto
    Date: 2021 May 21, 03:06 -0700

    Would anyone know if there are any realistic cases when using the NASR that you would encounter large negative F values, say -91°?

    I'm guessing this might occur in low latitudes taking a sunrise or sunset sight but maybe there are other realistic situations that can have large negative F values. 

    I have only been able to come up with a few realistic cases of negative F values but they are all around -1° or -2°. 

    If anyone has done a mathematical analysis on large negative F values I'd appreciate any insight on this as well.
