| contents | We calculate the classes of the universal hyperelliptic Weierstrass divisor $\bar{\mathcal H}_{g,w}$ and the universal $g^1_2$ divisor $\bar{\mathcal H}_{g,g^1_2}$. Our results are expressed in terms of a basis for $Cl(\bar{\mathcal H}_{g,1})$ and $Cl(\bar{\mathcal H}_{g,2})$ computed by Scavia. |
