We construct SO(2,1) x SO(3)-invariant half-BPS solutions in six-dimensional(0,4) supergravity with m tensor multiplets. The space-time manifold of eachone of these solutions consists of an AdS_2 x S^2 warped over a Riemann surfaceSigma with boundary. The most general local solution is parametrized by onereal harmonic function, and m+2 holomorphic functions which are subject to aquadratic constraint and a hermitian inequality, both of which are manifestlySO(2,m) invariant. Imposing suitable conditions on these harmonic andholomorphic functions, we construct globally regular supergravity solutionswith N distinct AdS_3 x S^3 asymptotic regions and contractible Sigma. Thesesolutions have an intricate moduli space, whose dimension equals 2(m+1)N -m-2and matches the counting of three-form charge vectors and un-attracted scalarsof the tensor multiplet. Exact explicit formulas for all supergravity fieldsare obtained in terms of the moduli. Our solutions give the near-horizongeometries for junctions of N self-dual strings in six dimensions, and areholographic duals to CFTs defined on N half-planes which share a commoninterface line. For m=5, the solutions lift to quarter-BPS solutions forsix-dimensional (4,4) supergravity.
