The emission of light flashes from sound driven bubbles in ethylene glycol at 20–23 °C has been temporally stabilized. The intensity of the light flashes is approximately twice that of SBSL in degassed water at 20 °C. The time jitter is less than 100 ns and the flashes spatially jitter less than 2 mm around stable positions near the pressure antinode of the second harmonic. The light flashes trace out periodic, continuous orbits within this small region. Sonoluminescence in ethylene glycol is relatively stable with temporally stabilized SBSL bubbles lasting up to 60 min.
