The magnetic field, current density, and energy of an arbitrary array of curved or straight flux lines in a type II superconductor with a planar surface are calculated from the London theory. The general expressions and their expansion with respect to displacements from the equilibrium flux-line positions are given. The elastic energy of the distorted flux-line lattice near a planar surface is presented and discussed. The equilibrium configuration becomes unstable to the growth of helical perturbations if a current exceeding a critical value is applied parallel to the external magnetic field.
