heal.abstract	In this note we examine whether spherically symmetric solutions in covariant Horava-Lifshitz gravity can reproduce Newtons Law in the IR limit λ→1. We adopt the position that the auxiliary field A is independent of the space-time metric, and we assume, as in, that λ is a running coupling constant. We show that under these assumptions, spherically symmetric solutions fail to restore the standard Newtonian physics in the IR limit λ→1, unless λ does not run, and has the fixed value λ=1. Finally, we comment on the Horava and Melby-Thompson approach in which A is assumed as a part of the space-time metric in the IR. © 2011 American Physical Society.	en
