    That is correct for your location and the observation time.

    W to E travel is expected of Lacrosse; never E to W. Are you certain that you
    did not follow an aircraft?
    
    If not an aircraft, I see three possible explanations:
    
    - observation time reduction error
    
    - tracked wrong satellite
    
    - tracked correct satellite, which was significantly early
    
    If you are certain of the time, and if you know any of your reference star
    pairs, then I suggest reducing them as is.
