Scientific paper

High-dispersion echelle spectra taken of the metal-deficient red giant HDE 232078 indicate that the mass loss rate of this star is highly variable. The time scale of the variability and the rate of mass loss is similar to Population I objects of similar temperature and luminosity. The nature of the variability also calls into question previous conclusions which indicate that the mass loss rate of globular cluster giants is independent of metallicity.
