  The NPDGamma experiment aims to measure the parity-odd correlation between
the neutron spin and the direction of the emitted photon in neutron-proton
capture. A parity violating asymmetry (to be measured to 10$^{-8}$) from this
process can be directly related to the strength of the hadronic weak
interaction between nucleons, specifically the $\Delta$I=1 contribution. As
part of the commissioning runs on the Fundamental Neutron Physics beamline at
the Spallation Neutron Source (SNS) at ORNL, the gamma-ray asymmetries from the
parity-violating capture of cold neutrons on $^{35}$Cl and $^{27}$Al were
measured, to check for systematic effects, false asymmetries, and backgrounds.
Early this year, the parahydrogen target for the production run of NPDGamma was
commissioned. Preliminary results for the commissioning measurements with
$^{35}$Cl and $^{27}$Al will be presented as well as first results of the
hydrogen run.
