Abstract
We report the discovery of a new X-ray transient AGN, RX J1624.9+7554. This object appeared to be bright in the ROSAT All-Sky Survey, but had turned o ff in two pointed observations about one and a half years later. The optica l identification spectrum shows a non-emission line spectrum of a spiral ga laxy at z=0.064. We will discuss several hypotheses that can explain the pe culiar behaviour of this object.
