Booming sounds across Dorset, Somerset, and Devon

Have we experienced another large bolide causing audible phenomena around 1500 UT today (2021 03 20)?

Would something have shown up on radar meteor watches?

The British Geological Survey say there has not been a seismic event to cause it.

Hi Richard,

Here's its IMO Fireball Event webpage

Fireball event (imo.net)

but almost all observers don't mention any sound. Is it the same event?

NEMETODE members didn't detect it on radio, but more checks awaited...

Cheers,

     Alex.

Yes, I heard it this

Yes, I heard it this afternoon in Sidmouth. Thought it was gunfire practice off Portland. Apparently heard as far away as Normandy. David

Radio echoes

I use GRAVES transmitter and received 15 meteor events between 1430 and 1530 UTC yesterday, 20/3/21. The largest of these was at 15:07:19 and the signiture was that of an underdense meteor with a head-echo. The duration was 0.37 seconds.   On a subjective assessment the recieved scatter signal was moderate for me in Derbyshire and nothing special.   

Updated after seeing IMO page which makes it earlier than my event.  I guess the geometry wasn't rignt for scatter for my location.

Here's the Sat24 image from 15:00 UT yesterday which shows the cloud cover that masked views of the fireball from southern England

Cheers,

Booming fireball

What a shame it was cloudy here.

My wife was gardening and the sounds were unmistakable as they went on for nearly 10 seconds she reported. Sadly looks to have undergone a watery end in The Channel. Thanks for everyone's contributions.

No signal detected on my

No signal detected on my Gravers radio system.

In fact, it was so quiet at the time, I wondered if Graves was actually active.

A previous fireball in this area generated a very strong signal.

Regards,

Michael.
