The smoke came after a terminal flash. It lasted very shortly, but I saw the smoke during the flash.
Terminal flash
Observation
Yes
Remarks
There was a huge green flash which made me look up to see a large fireball (looked bigger than Venus, or it was close) that created orange "sparks" that looked like flint and steel came together. The sparks had very small amounts of streaking which lead me to think that these could have been fragments.
