My meteor cameras picked up another propellant dump last night (August 25) from Chelmsford. This was from the Chinese CZ-8A launch at 1908 UTC from Hainan. The payload consisted of nine satellites for the SatNet constellation.
The cloud was first seen by my west facing UK004G camera as it rose into the field of view at 2032 UTC. It passed almost through the zenith and then entered the field of view of my east facing camera UK004J at 2039UTC. The cloud was preceeded by a line of points which, presumably, were the payload.
The real time video is here:

This lasts 10 minutes so, if you have a limited attention span as I do, I recommend this version which is speeded up by a factor of 100:
