Hunga Tonga eruption can be seen in BME280!

Hello,

it is fascinating, that the air blast wave from eruption of Hunga Tonga–Hunga Haʻapai volcano on 15th jan 2022 04:14:14 UTC could be registered in germany with a simple BME280 pressure sensor.
As measured by official stations, a first wave passed at approx. 19:30 UTC, see

With 1235km/h for the speed of sound and a distance of approx. 20000km the time to reach europe is in the order of 16 hours…

My own sensor showed this even more clearly, but how can images be uploaded here?

The eruption is described in

Nice, i was already wondering from what direction the pressure wave came.

And another video where you can also see the second wave some hours later (near the end of the video):
