Zusammenfassung:A bstract We investigate the presence of logarithmic CFT doublets in the soft sector of celestial CFT related with supertranslations. We show that the quantum operator associated with a log u late-time behavior for the asymptotic gravitational shear forms a logarithmic CFT pair of conformal dimension ∆ = 1 with an IR-regulated supertranslation Goldstone current. We discuss this result in connection with previous encounters of log CFT structures in the IR-finite part of celestial OPEs.
