We present results from STAR's first dedicated fixed-target run conducted in 2015 with Au + Au collisions at sNN=4.5GeV. Directed flow of protons and lambdas, elliptic flow of identified hadrons, HBT radii, as well as pion, Ks0, and Λ spectra are compared with previous results from the AGS. These results demonstrate that STAR has good event reconstruction and particle identification capabilities in the fixed-target configuration. The implications of these results on future STAR fixed-target runs are discussed.
