Ac-susceptibility and dc-magnetization measurements provide solid evidence for bulk superconductivity with a volume fraction of $\\sim 70\\%$. The lower critical field is surprisingly small: $B_{c1} = 0.008$ mT $(T \\rightarrow 0)$. Muon spin rotation experiments in a transverse magnetic field of 0.01 T show a weak increase of the Gaussian damping rate $\\sigma_{TF}$ below $T_c$, which yields a London penetration depth $\\lambda = 1.6 \\pm 0.2~ \\mu$m.
