We present a catalog of 430 field horizontal branch (FHB) stars, selected from the Hamburg/ESO Survey (HES), which fortuitously align with high column density neutral hydrogen (HI) high-velocity cloud (HVC) gas. These stars are ideal candidates for absorption-line studies of HVCs, attempts at which have been made for almost 40 years with little success. A parent sample of 8321 HES FHB stars (Christlieb et al., 2005, Cat. ) was used to extract HI spectra along each line of sight, using the HI Parkes All-Sky Survey (Putman et al., 2002, Cat. ). All lines of sight aligned with high-velocity HI emission with peak brightness temperatures greater than 120mK were examined. The HI spectra of these 430 probes were visually screened and cross-referenced with several HVC catalogs.
