A method for measuring the helicity beam asymmetry (I{sub {center_dot}}is shown and demonstrated using the reaction {gamma}p{yields}p{pi}{sup 0{eta}}. The very preliminary results for this channel are presented and suggest that the helicity beam asymmetry is small. The statistics for this channel in this analysis are limited making an analysis of angular dependencies difficult.
