A flux of neutrons from an astrophysical source within our Galaxy would be detected by the Pierre Auger surface detector as an excess of air showers arriving from the direction of the source. In order to reduce thestatistical penalty incurred by multiple trials, classes of candidate sources are analyzed collectively as target sets or ?stacks?. Individual candidate sources are weighted in proportion to their electromagnetic flux and to their exposure to the Auger Observatory. The results are summarized as a combined p-value for each of the stacks, along withinformation about the candidate source with the minimum individual p-value in each stack. No significant excess flux is found from the targets considered.
