Energies of the circular (nℓ= n - 1) 1 ≤ n ≤ 20 levels have been calculated for hydrogenlike sigmonic atoms with 1 ≤ Z ≤ 92, using the current world average sigma mass, as well as the electronic shift in Σ- + Ne e- + nucleus systems, where Ne stands for the number of electrons. The electronic influence on sigmonic orbitals has also been investigated through the computation of the hyperfine structure and the anomalous Σ- magnetic moment effects in sigmonic Be 2p states.
