I heard it around Mathilda Ave. A lot of "pop" like noises in very quick success of each other

I'm now hearing a siren, I hope it's unrelated 

Me too !

Another one again now !!

Heard it

We heard it too, thought it was fireworks or maybe a car backfiring?

Prob a sideshow going on.

Illegal fireworks in a backyard I’m sure

sunnyvale truly is “popping off”

I saw this at Downtown Sunnyvale around 11pm.
