TITLE: GCN CIRCULAR NUMBER: 10970 SUBJECT: GRB 100724A: fading afterglow seen with GROND DATE: 10/07/24 02:16:21 GMT FROM: Sylvio Klose at TLS Tautenburg F. Olivares E., J. Greiner, P. Afonso (all MPE Garching), and S. Klose (TLS Tautenburg), report on behalf of the GROND team: The afterglow candidate reported by Olivares et al. (GCN 10969) is clearly fading. Between mid-times of 00:49 UT and 01:14 UT the object faded by 1.3 magnitudes, corresponding to a power-law decay index of about 0.7. We therefore confirm this object to be the afterglow of GRB 100724A.
