We have discovered a transient X-ray source, RX J1420.4+5334, which displays a ROSAT flux variation of 150 between the ROSATAll-Sky-Survey in 1990 and a preceding pointed ROSAT observations in July 1990. Optical observations suggest a non-active galaxy as the only visible counterpart. We therefore tentatively identify RX J1420.4+5334 as a tidal disruption event in a non-active galaxy.
