Was there one recorded 8.21am today Tues 18/01?

Was checking something on my computer before work, heard what sounded like a sonic boom (like a cardboard box full of glass pieces hitting the ground) and the power lines to my house and all down the street swayed intensely before settling. Seemed pretty clearly a shock wave.

Nothing reported on the news yet (9.42am)
