TITLE: GCN CIRCULAR NUMBER: 21338 SUBJECT: Correction to GCN Circular 21337: GRB 170710D CALET Gamma-Ray Burst Monitor detection DATE: 17/07/14 07:44:25 GMT FROM: Takanori Sakamoto at AGU T. Sakamoto (AGU) and the CALET collaboration We named the GRB wrongly in our previous GCN circular (Tamura et al. GCN Circ. 21337). The correct GRB name is GRB 170710D not GRB 170710C (since GRB 170710C was already named for the GRB detected by INTEGRAL on 05:05:15 UT; Mereghetti et al. GCN Circ. 21326). Apologies for any confusion caused. We would like to thank Sandro Mereghetti for pointing out this error.
