TITLE: GCN CIRCULAR NUMBER: 17948 SUBJECT: V404 Cyg: Fermi GBM observations DATE: 15/06/19 22:19:19 GMT FROM: Eric Burns at U of Alabama E. Burns (UAH), P. Jenke (UAH), B. Mailyan (UAH), G. Younes (GWU), and A. von Kienlin (MPE) report on behalf of the Fermi GBM Team: "The Fermi Gamma-Ray Burst Monitor has triggered multiple times on the current outburst of V404 Cyg. These triggers have all been misclassified as GRBs by the flight software. A list of V404 Cyg triggers up to now is listed below. It is likely that there will be more triggers from this source as long as it remains active and we will not issue circulars for these triggers. We will populate our online trigger catalog with the correct classification as soon as possible. The online trigger catalog is updated automatically by the HEASARC once per day. A list of V404 Cyg triggers can be found by searching for the 'TRANSNT' trigger type and confirming the location. The catalog can be browsed at: http://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigtrig.html Triggers that our duty scientist classifies as GRBs are followed by GCN notices with a final human-in-loop localization with a latency of 30 minutes to a few hours after the trigger. Triggers that are not classified by a human as GRBs are not followed by final position GCN notices. Triggers from V404 Cyg to date: 150619774/456431653 150619580/456414880 150619570/456414027 150619561/456413265 150619554/456412636 150619427/456401723 150619420/456401105 150619352/456395199 150619342/456394328 150619317/456392148 150619309/456391510 150619301/456390804 150619242/456385736 150619224/456384186 150619173/456379743 150619165/456379080 150618834/456350498 150618763/456344362 150618710/456339724 150616921/456185211 150616855/456179459 150616734/456169002 150615798/456088185 150615791/456087544"
