  We calculate the elliptic flow of bottomonia produced in Pb$\,+\,$Pb
collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV. We consider temperature-dependent
decay widths for the anisotropic escape of various bottomonium states and
observe that the transverse momentum dependence of bottomonia elliptic flow
provides a tomographic information about the QGP fireball at different stages
of its evolution. For the space-time evolution of the fireball, we employ
simulation results from the 3+1D quasiparticle anisotropic hydrodynamic model.
We find that our results for transverse momentum dependence of bottomonia
elliptic flow are in reasonable agreement with experimental results from the
ALICE and CMS collaborations.
