Immediate flash (7)

Ross

I believe the answer is:

instant

This clue is a double definition.

'immediate' is the first definition.
(I've seen this in another clue)

'flash' is the second definition.
(I know that flash can be written as instant)

(Other definitions for instant that I've seen before include "Sudden; moment" , "Occurring immediately, like some fast food" , "Fast, flash" , "Trice" , "Precise moment" .)

I've seen this clue in The Times and The Telegraph.
