The BESIII experiment at the Beijing Electron Positron collider, run as a``hyperon factory'', recently reported the first measurement of the asymmetryparameter of the $\Lambda\to n\gamma$ decay and updated its branching fraction,which differs from the PDG average by 5.6 sigma. We highlight the impact ofthis new measurement on our understanding of the puzzle of weak radiativehyperon decays and pinpoint what needs to be done in the future.

Are we close to solving the puzzle of weak radiative hyperon decays?
