I haven’t concluded if there was a ground event but was quite interested that another person saw something and reported it at the same approximation.

Remarks
I saw a instant bright orange flash on the horizon in the direction of Stratford or London I would guess. As a fire fighter my first concern was an explosion but there was a second one moments after the first one. May be a minute but not not more.
