We describe the geometry of the $ mathbb{R} imes { ext{SO}}(3) imes { ext{SO}}(6) imes { ext{U}}(1) $ invariant half-BPS M-theory configurations considered in LLM in terms of their electrostatic variables. We discuss both regular configurations, such as AdS4 × S7 and AdS7 × S4 vacua or simple excited solutions, and singular ones such as the superstar geometries. This allows us to identify the appropriate boundary conditions describing the most general smooth and superstar-like singular configurations. We also compute their masses, matching the expected result from their microscopic interpretation, but now at finite radius of curvature.
