Ring hotline with a strange name (9)

I believe the answer is:

anthelion

'ring' is the definition.
(thesaurus)

'hotline with a strange name' is the wordplay.
'with' is a charade indicator (letters next to each other).
'strange' indicates anagramming the letters.
'name' becomes 'n' (common abbreviation e.g. on forms).
'hotline' after 'a' is 'ahotline'.
'ahotline' anagrammed gives 'anthelio'.
'anthelio'+'n'='ANTHELION'

(Another definition for anthelion that I've seen is " seen in the heavens".)

I've seen this clue in The Times.
