Query: Beam Normal Single Spin Asymmetry Measurements from QWeak   The Q weak experiment has made several interesting beam normal single spin
asymmetry measurements. Preliminary result from a 3.2% measurement of the beam
normal single spin asymmetry in elastic e+p scattering at E = 1.155 GeV and
{\theta} lab = 7.8(deg) is presented. We have also made measurements of this
asymmetry in elastic and inelastic scattering in the Delta resonance region
from Hydrogen, Aluminum and Carbon targets and e+e scattering from Hydrogen
target. Some initial results from these measurements are also presented.
