  We identify the spectral curve of pure gauge SU(2) Seiberg-Witten theory with
the Weierstrass curve $\mathbbm{C}/L \ni z \mapsto (1,\wp(z),\wp(z)')$ and
thereby obtain explicitely a modular form from which the moduli space parameter
$u$ and lattice parameters $a$, $a_D$ can be derived in terms of modular
respectively theta functions. We further discuss its relationship with the
$c=-2$ triplet model conformal field theory.
