The near horizon aspects (and beyond) of a black hole metric, which belongsto a large class of static spherically symmetric black holes, are consideredhere. It has been realized recently that an atom falling into a black holeleads to the generation of acceleration radiation through virtual transitions.In recent studies, it has been argued that this acceleration radiation can beunderstood from the near horizon physics of the black hole. The near horizonapproximation leads to conformal symmetry in the problem. We go beyond the nearhorizon approximation in our analysis. This breaks the conformal symmetryassociated with the near horizon physics of the black hole geometry. We observethat even without the consideration of the conformal symmetry, the modifiedequivalence relation holds. Further, our analysis reveals that the probabilityof virtual transition retains its Planck like form with the amplitude gettingmodified due to the beyond near horizon approximation. For the next part of ouranalysis, we have observed the horizon brightened acceleration radiationentropy (HBAR) for a Garfinkle-Horowitz-Strominger (GHS) black hole. We observethat the HBAR entropy misses out on quantum gravity like corrections whileconsidering the conformal case. However, such corrections emerge when theconformal symmetry gets broken in the beyond near horizon analysis.
