Stars turning up in ordinary locations (4)
I believe the answer is:
lyra
'stars' is the definition.
(I've seen this before)
'turning up in ordinary locations' is the wordplay.
'turning up' says the letters should be written in reverse.
'in' says the answer is hidden in the clue.
'aryl' is hidden in the letters of 'ordinary locations'.
'aryl' back-to-front is 'LYRA'.
(Other definitions for lyra that I've seen before include "Constellation resembling a musical instrument" , "Asriel's child" , "Collection of stars" , "Constellation representing instrument of Orpheus" , "Constellation near Draco" .)
