It was near calm so not much headway was made. A bit after 1600 local time, a lunar distance observation was made between the sun and the moon. The following observations were made in the order listed.

Time again for another navigation exercise from places far afield from
land. For this one, we'll pretend I don't have much of a clue where i am
or what time it is.
For the following problems assume the following. IC -0.8' arc, height
of eye 106 feet, T/P is 94 deg F, 1007 MB, ZD-6
While sailing near the Chagos Archipelago a LAN observation was
made on board a ship on 24 March 2010. The star starts to hang when
the watch says its 13h 18m and an Hs of the lower limb is recorded at
81 degrees 34.7' as the navigator faced north. What is your best guess for
Latitude at that time?

Sun LL Hs 45-29.8'
Moon UL Hs 23-33.4'
Ds 102-44.6'
Sun LL Hs 44-10.8'
Moon UL Hs 24-23.9'
What is the approximate UTC?
Have fun
