The excess in electron recoil events reported recently by the XENON1T experiment may be interpreted as evidence for a sizable transition magnetic moment of Majorana neutrinos. We show the consistency of this scenario when a single component transition magnetic moment takes values ϵ (1.65 - 3.42) × $10^{-11}$ $\mu_B$. Such a large value typically leads to unacceptably large neutrino masses. We...
