Crossword Genius

A flash, perhaps, and a bang (6)

Ross

I believe the answer is:

report

I believe this is a double definition.

'a flash perhaps' is the first definition.
(flash is a kind of report)

'a bang' is the second definition.
(I've seen this before)

'and' acts as a link.

(Other definitions for report that I've seen before include "Relate; gun noise" , "Make a complaint about (someone)" , "Narrative given by porter" , "'Description, account (6)'" , "Written account" .)
