Spectra of the Herbig Ae Be star HD 163296 show variability in the CO and OH ro-vibrational emission lines. Documented here is the variance of OH emission lines between measurements separated by a period of three years. By comparing this variability to the variability of CO, we aim to determine whether the two are linked through an event such as disk winds. We find the profiles of OH and CO taken within three months of each other to have exceedingly similar profile shapes. However, the variability seen between the OH data sets needs further work to verify whether the changes we see are reproducible.
