What follows is *SPECULATION*, but RE the reports of a loud #sonicboom heard across the Westcountry at just before 3pm: I wonder if the bright *transitory* feature which appears at 14:50pm over the Bristol Channel in this sat image could be significant?https://meteologix.com/uk/satellite/b81dd63762cb17c3a7f7087fb61e6255/satellite-hd-5min/20210320-1450z.html …
That feature isn't there in data 5 mins before or after. Given sound was so widely heard, the RAF have told some outlets it wasn't their planes & there's nothing I can see on the live BGS seismograms, there's a part of my brain wondering if this could have been a meteor bolide?
And, look, there's this visual report from Wales concurrent with the timing of the #sonicboom:https://twitter.com/peninsulabirds/status/1373291862979661826 …
So the question is: was there anyone else in the bit of west Wales that had clear skies at ~14:50 today that *also* saw something that sounds very much like a meteor bolide.
Perhaps @BBCRadioWales or @bbcsomerset listeners might be able to help?
Worth noting that *if* (and that's a big IF) this was a bolide, then these can sometimes be registered by US government satellites. These are then sometimes listed at https://cneos.jpl.nasa.gov/fireballs/ , but I'm not sure what the update frequency is on those listings...
And now reports of a 'disintegrating' meteor being seen -- at the same time as sonic boom heard in UK -- from north-west France.

And there you have it!

As a coda to this thread [which was fun to piece together in 'real-time', I have to say]:
If anyone observed/filmed the #meteor #bolide at 14:53UT today (from the Westcountry/Wales/France/Channel Islands etc.), please submit reports to @UKMeteorNetwork:https://ukmeteornetwork.co.uk/fireball-report/ …
We saw how scientifically important such reports and national/international collaboration between members of the public and scientists were with the #Winchcombe #meteorite.
You never know how your piece of information fits into the bigger picture!
Adding more info as I can to this thread on the #meteor #bolide:
The dashcam footage from Jersey [https://twitter.com/willgater/status/1373327945863987210 …] was taken from the road in St Helier here: https://www.google.co.uk/maps/@49.1818832,-2.1085883,106m/data=!3m1!1e3 ….
The bolide appears first (roughly) in the NW and then tracks rapidly towards due N.
OK. Here it is!
This afternoon's UK #meteor #bolide over the skies of the Bristol Channel (it's the little bright spot that appears just off the coast near Minehead).
This data was kindly processed for me by @simon_sat (thanks, Simon!)

For completeness, here is probably the best recording I know of of the #sonicboom likely associated with today's #meteor #bolide. https://twitter.com/EastFleetFarm/status/1373332308254687233?s=20 …
Would *love* to know exactly how accurate that time stamp is, as could be handy to cross-reference with the dashcam video.
Here's some really decent audio of the #sonicboom, recorded by a birder in Dorset, showing just how long the rumbling lasted.

#meteor #bolide
Had some Qs about whether yesterday's #meteor could be connected to the #Winchcombe fall.
Short answer: no - 
moves ~2.5 million km in its orbit each day, meaning we're over 50 million km further around the Sun; so the two space rocks would have been a long way apart in space.
Wow! Fantastic images here of yesterday's daylight #meteor #bolide, as seen from Jersey.

Update on Saturday's bolide #meteor story: I've been in contact with NATS, who look after UK airspace/ATC. No sign of the meteor, or falling meteorites, on their radar systems.
