### Description

The Event Plane Detector (EPD) is an upgrade to the STAR experiment that will significantly improve event plane resolution and provide a measure of collision centrality at forward rapidity ($2.1<|\eta|<5.1$). The complete detector, composed of two scintillator wheels at $\pm\eta$ and 2.1$<$$|\eta|$$<$5.1, will be operational in the 2018 run, but in 2017, a quarter of one wheel was commissioned. Results from this run including the partial EPD from Au+Au collisions at $\sqrt{\rm s_{\rm NN}}$$=54 GeV will be presented. The track densities at this energy are considerably higher than those expected for RHIC Beam Energy Scan energies (\sqrt{\rm s_{\rm NN}}$$\leq$20 GeV) for which the detector was originally designed. Nevertheless, the detector performed very well in this higher density environment. Preliminary pseudorapidity distributions and anisotropic flow ($v_1$ and $v_2$) results will be shown for forward rapidities measured by the EPD during the 2017 run.
