Peter,
That is a classic observation but perhaps doesn’t conform to the Meteor Section’s rules!
Pete Lawrence also got it from Selsey and his excellent image is on the spaceweather.com front page today. This has allowed us to confirm that the track started at the Orwell Estuary and ended somewhere around Bradwell on the Dengie so it would have been to the north of you. From comparison with the Moon the terminal burst was brighter than mag -12 for around 80ms or so.
Nick.
