We present an estimate of certain higher order corrections to the contribution of the charm triangle loop in the inclusive B -> X_s gamma decay rate, recently discussed by Voloshin. We find that these corrections are minute and hence the result found by Voloshin, although small, is quite robust.

Update of the nonlocal sub-leading ${O}_1$-${O}_7$ contribution to $\bar B \to X_s \gamma$ at LO
Updated leading-order calculation of the complete non-local O1-O7 contribution to inclusive B-bar to Xs gamma decay, incorporating correlations with the local Voloshin term and revising its range.
