TITLE: GCN CIRCULAR NUMBER: 28563 SUBJECT: GRB 201006A is likely a short burst DATE: 20/10/06 17:04:58 GMT FROM: Aaron Tohuvavohu at U Toronto GRB 201006A, detected by Swift/BAT (Gropp et al. GCN 28560), INTEGRAL/IBAS (Mereghetti et al. GCN 28561) and Fermi/GBM (trig num 623639877), appears likely to be a short burst, despite the real-time duration estimate (~5s) reported in GCN 28560. The T90 estimate from downlinked Swift/BAT event data is less than 0.5 seconds. Follow-up is encouraged.
