PESSTO (Public ESO Spectroscopic Survey of Transient Objects) is a public spectroscopic survey targeting supernovae and optical transients brighter than 20.5 mag. with the goal of classifying them as close as possible to their explosion phase. Data Release 1 contained more than 900 flux calibrated spectra for 298 distinct objects observed during the first year of the survey. These spectra are now complemented with release of 234 reduced and calibrated near-infrared SOFI images for 22 transient objects. The images, and the spectra, can be queried and downloaded from the Science Archive Facility.
