Find position in the east (6)
I believe the answer is:
orient
This clue is a double definition.
'find position' is the first definition.
'east' is the second definition.
('orient' can be a synonym of 'east')
'in the' acts as a link.
(Other definitions for orient that I've seen before include "Adjust to surroundings" , "43 [POSITION]" , "Align; eastern" , "Establish one's position" , "Align; pearl" .)
