I believe the answer is:

elmo

(Other definitions for elmo that I've seen before include "Saint whose "fire" occurs around masts etc" , "Saint whose fire is electric!" , "Puppet character" , "St ...'s fire, weather phenomenon of coloured glow" , "St ----'s Fire: aura from electrical discharge" .)

I've seen this clue in the LA Times.
