Abstract
A differential invariant is found for null fields of arbitrary spin. For null gravitational fields, the invariant is identified as that of Bičác and Pravda; its derivation from the Bel-Robinson tensor is given; and a simple expression is found for its value in null perturbations of flat spacetimes.
