  The STEREO experiment is designed to test the hypothesis of light sterile
neutrinos being the cause of the Reactor Antineutrino Anomaly. It measures the
antineutrino energy spectrum from the compact core of the ILL research reactor
in six identical detector cells covering baselines between 9 and 11 m. Results
from 119 days of reactor turned on and 211 days of reactor turned off are
reported. Using a direct comparison between neutrino interaction rates of all
cells, independent of any flux prediction, we find compatibility with the null
oscillation hypothesis. The best fit point of the Reactor Antineutrino Anomaly
is rejected at 99% C.L.
