We have discovered among SDSS-DR6, in Dec. 2007, a galaxy which is unique in showing super-strong high-ionization iron lines and very unusual double-peaked Balmer lines which are fading away, but have not yet disappeared. The high degree of line ionization implies that we see the light-echo of an (unobserved) EUV-X-ray flare. We have confirmed, with optical ToO photometry on Jan. 1, 2008 the low-energy tail of this flare in the optical and NIR. Only a few X-ray flaring galaxies are known. This is the first time we have seen such a broad line and continuum response. With Chandra, we will for the first time detect the actual X-rays from this flare, characterize the X-ray emission, locate the flare within 1 kpc of the nucleus, and test the favored scenario - tidal disruption of a star - before the flare has faded away. Depending on the measured source's X-ray brightness, we will then consider X-ray monitoring to map the emission-line changes in response to the X-ray fading.
