    Here is my solution.
    
    
    INITIAL DATA
    
    17:07:18.5 UT1 (from Kermit's original message July 19)
    +16.4 s ∆T
    S16°45' W151°35' (= -16.75° -151.55°) assumed position
    105°47'04" (= 105.7844°) lunar distance, limb to limb
    43°29'00" (= 43.4833°) Moon refacted upper limb
    12°38'24" (= 12.6400°) Sun refracted lower limb
    3'50" (= .0639°) dip
    77.5° temperature
    
    
    SOLUTION
    
    Adjust time only:
    17:06:57.9 UT1
    +.5705° (= +34.25') Moon altitude intercept
    -.5007° (= -30.04') Sun altitude intercept
    (intercept = observed - computed)
    -.178°/min Moon altitude rate
    +.236°/min Sun altitude rate
    -.0037°/min topocentric lunar distance rate
    
    Adjust time and position:
    17:05:54.82 UT1
    -16.5108° -151.8963° (= S16°30.65' W151°53.78')
