Took me a while to recognize this

I noticed things like this before when looking back over collected data:

I was just looking at the live data stream and saw one currently active. It suddenly dawned on me that what I was looking at was out washing machine on its spin-dry cycle. Watching it to the end confirmed it, as the spin cycle ended and the drum slowed, so the trace I was watching dropped off.

I am more than a little surprised that my S-Boom picked this up. Based upon this Google Earth measurement, the washer and S-Boom are ~32m apart.


@Stormchaser I don’t think this is the appropriate group for this. It is NOT infrasound, it is vibration picked up by the seismometer…

Checking, there is some signal on the infrasound, but not as clear.
