Jun 19, 1997 · GRB 970616 The transient X-ray XTE source reported below by F. Marshall et al. lies in the error box of a gamma-ray burst seen by BATSE on June 16.757 UT.
We report on near-infrared and optical obser- vations of the GRB 970616 error box and of the X-ray sources discovered by ASCA and ROSAT in the region.

We use these scaling laws to discuss the afterglows of GRB 970228 and GRB 970616, and find that if the spectral index of the electron distribution is p = 2.5, implied from the spectra of GRBs, the X-ray afterglow of GRB 970616 is well fitted by assuming k = 2.
The object is located about 4'.5 away from the southern edge of the XTE/IPN error box, and hence it is not likely to be the afterglow of GRB 970616. This was the only fast fading object in the GRB 970616 field on our frames.
