We construct a differential operator on sheaves of p-adic modular forms defined over the locus of p-rank ≥ 1 of the Siegel threefold, by applying a revisited version of the approach that Sean Howe recently introduced in his paper "A unipotent circle action on p-adic modular forms" (2020, Trans. Am. Math. Soc.) to construct the theta operator in the elliptic case.
