We probe the nature of the so-called \"WEAK\" INTEGRAL triggers, when the gamma-ray instruments record intensity spikes that are below the usual STRONG significance thresholds. In a targeted Swift follow-up campaign, we observed 15 WEAK triggers. We find six of these can be classified as GRBs. This includes GRB150305A, a GRB discovered from our campaign alone. We also identified a source coincident with one trigger, IGRW151019, as a candidate AGN. We show that real ","authors_text":"A. B. Higgins, A. J. Bird, A. Rowlinson, D. G\\\"otz, J. P. Osborne, K.
