From the Astronomical Register at the Royal Observatory of Greenwich:
A very fine meteor was visible soon after midnight on June 27 last, and a good many observers have described its unusual brilliancy ‘ but with one or two exceptions they have not given exact particulars of its apparent path amongst the stars.
The meteor was fortunately observed by Mr A. M. W. Downing, of the Royal Observatory, Greenwich, as follows:-
June 27, 12h 15m G.M.T. – As I was crossing Blackheath I saw an extraordinarily brilliant meteor. The path was from Cassiopeia to near Pegasi, where it disappeared. It was many times brighter than Jupiter, left a bright train, and moved slowly, duration quite 5 seconds. It was the most remarkable and brightest meteor I have ever seen.
