For reference usually I see very thin wisps of NO2 at the lip of the beaker by the watch glass that become invisible as soon as they mix with the air, this was throwing out enough that I saw visible brown puffs moving up from the beaker and remaining visible all the way up to the top of the hood. Faint, but visible.
