First results from the sPHENIX experiment on the π⁰ v₂ and dE_T =dη in Au+Au collisions at $$\sqrt{s_{NN}}$$ = 200 GeV using detector commissioning data during the RHIC 2023 Run are presented. These results are shown across a large centrality range, and compared to previous PHENIX and STAR results. These measurements demonstrate the sPHENIX capabilities towards accomplishing the sPHENIX jet physics program. From the ongoing RHIC 2024 Run, p + p collisions at $$\sqrt{s}$$ = 200 GeV, a first glimpse of the measurements K_S⁰ and Λ⁰ obtained by the sPHENIX Time Projection Chamber (TPC) detector are shown.
