The CfA Optical/Infrared Telescope Data Center is pleased to announce a new public archive of processed spectra obtained from CfA’s ground-based telescopes. The initial release contains 200,000 spectra from the optical Hectospec spectrograph on the 6.5-m MMT; more spectra and more instruments will be added in the future. The web interface is user-friendly. The archive is virtual-observatory compliant and can also be accessed by pointing TopCat, Aladin, or other VO tools to the “CfA Hectospec” SSAP service.
