The Caspec échelle spectrograph at the ESO 3.6m telescope was used to obtain high resolution spectra for Arp 1145, and the star 2 of the metal-rich cluster Terzan 1. Arp 1145 was selected from Pickles & van der Kruit (1990). The star Tz1-2 was selected from Terzan 1 BVRI photometry carried out by Ortolani, Bica & Barbuy (1993) New HST CMDs show that Terzan 1 appears to be located nearby the Galactic center.
