NOTES:

A lunar observation is an observation of the moon that is extremely difficult to take
and calculate due to the rapid movement of the moon and the myriad corrections that
have to be made to the sextant reading. A lunar observation alone will not discern
longitude but has to be crossed with another observation to obtain a position.
