Abstract: We complete the classification of local stability thresholds for smooth del Pezzo surfaces of degree 2. In particular, we show that this number is irrational if and only if the tangent plane at the point intersecting the surface is the union of a line and a smooth cubic curve meeting transversally at the point.
