I thought there was still monitors on the moon. I remember a report a year or two ago about something causing
the moon to “ring like a bell”.

I thought there were too, but when I searched it was stated that the Apollo seismometers were all shut down in 1977 due to budget issues, and there are apparently no others on the moon presently. I was surprised.

So Johnny B. Goode was on the moon?

" I remember a report a year or two ago about something causing the moon to 'ring like a bell'.

I remember that as well. It might have been part of a study done using some space hardware to impact the moon and then measuring the seismic response. That may go back to the 70's.
