Scientific paper

One of the gamma-ray bursts localized by the RXTE ASM was followed by ASCA and ROSAT HRI pointings. While an X-ray source was detected just outside the ASM error box, it was never associated with the GRB because it was not clearly fading and because no optical afterglow was found. Years later, while attempting to identify an EGRET source whose error ellipse includes the position of GRB 970815, we made deep optical observations of the ASCA and ROSAT source position, which is still blank to a limit V > 24.4. We need a brief Chandra observation to see if the X-ray source is persistent. If not, it was almost certainly the X-ray afterglow of the optically "dark" GRB. If still present, it may be an "off-beam" pulsar counterpart of an EGRET source, and an important target for further study.
