Query: Effect of small cosmological constant on electromagnetic memory effect   We consider a generic scattering process that takes place in a region of size
R inside the static patch of the de Sitter spacetime such that R is smaller
than the curvature length scale of the background. The effect of curvature can
thus be studied perturbatively. We obtain the asymptotic electromagnetic field
generated by the scattering process including the leading order correction due
to the presence of de Sitter background and discuss its universal aspects. We
finally caculate the resultant first order corrections to the flat spacetime
velocity memory effect.
