These screen shots are from the first detection in infrasound that I'm confident is a meteor. The wave form is the classic N shaped wave of of a class I meteor. Class II meteors have a double N shape (peak, trough, peak, trough), Class III meteors have a triple N shape and Class IV covers all larger numbers of peaks and troughs in the signature (so usually larger bolides).


First image is the wave form as detected on my Shake and Boom.
The second image is the spectrogram (frequency analysis v time) of the wave form.
The third image is the wave form as displayed on ShakeNet after calibration of the signal to indicate pressure in Pascals.
Times are in UTC except for the pressure graph which is AEDT.



If anyone would like to have a look at the live stream data from my Shake and Boom, it is can be found on the ShakeNet website in Data view and my Shake and Boom is R21C0. EHZ is the seismograph channels (vertical) and HDF is the infrasound channel. You can also view live data from any other Raspberry Shake and/or Boom installed anywhere in the world on ShakeNet.
