Disturbance of our area, those polar lights? (7)
I believe the answer is:
aurorae
'polar lights?' is the definition.
(I've seen this in another clue)
'disturbance of our area' is the wordplay.
'disturbance of' is an anagram indicator (I've seen this in other clues).
'our'+'area'='ourarea'
'ourarea' with letters rearranged gives 'AURORAE'.
'those' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for aurorae that I've seen before include "Flashes of light" , "Phenomena" .)
