Hi George

Rather than turning LAT into LMT and then adjusting LMT for the difference in 
longitude from
the central meridian, just use LAT directly.

Using the LAT and differencing us from the GMT as defined by the exercise, we get

15-48-17 (time)
06-54-00 (time)
-- -- -- -- -
08-54-17 (time)

Turning time into arc we obtain
133 degrees 34 minutes and 15 seconds WEST (arc)

But the DR Longitude in the log is 227 degrees 40.5 minutes EAST (arc)

These should add to 360 degrees.   They do not

133  34  15
227  40  30
-- -- -- -- ---
360 74 45
or
361 degrees 14 minutes 45 seconds

Hmmmm.  Are the altitudes OBSERVED and hence in error????

The sun's altitude is given as 5 degrees, 41 3/4 minutes.  This is well below the 
nominal 10 degrees
rule of thumb for altitude limits.  Could refraction be playing a part here?

The moon's altitude is given as 10 degrees 31 7/8 minutes.  While above 10 
degrees, it also
suffers from the bright patch on the sea reflected from the moon.

Best Regards
Brad
