Violin Base Glitch

The LIGO detectors produce data with many short-duration bursts of noise (glitches) that obscure gravitational wave signals and can indicate problems with the detector. The Gravity-Spy project uses machine learning and citizen scientist volunteers to classify glitches so that their causes can be investigated. The volunteers can propose new glitch categories when they encounter glitches that do not seem to fit existing categories. I am investigating a proposed glitch category called Violin and Base. It has a high frequency noise burst around 1016.44 Hz and low frequency noise bursts about 20 to 50 Hz bursts. Currently I think the glitch is caused by a malfunctioning coil driver chassis.
