GRB | Session 62 | 1-3 Sep 2015

27. The Chair presented a list of possible issues for the future GRB activities prepared at an informal meeting convened by the Chair in July 2015 (GRB-62-08). Various experts expressed their interest in pursuing specific items on the list and/or proposed new subjects. To take these comments into account and to prepare an updated and prioritized list, the Chair informed GRB about his intention to convene a second meeting of stakeholders at the beginning of December 2015, the results of which would be reported to the next session of GRB.
