TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1815 SUBJECT: Distribution of INTEGRAL SPI-ACS triggers for GRB bursts DATE: 03/01/15 17:18:01 GMT FROM: INTEGRAL Shift Ops at INTEGRAL The ISDC Shift Team and the INTEGRAL SPI-ACS GRB Team report: This circular concerns GRBs detected in the SPI-ACS data . It is complementary to GCN circular 1813 dealing with GRBs detected in the field of view of INTEGRAL. A new procedure for the distribution of INTEGRAL SPI-ACS triggers has been decided during the INTEGRAL-IBAS meeting on 2003 Jan, 14: The automatic alert generation is foreseen to start in the next weeks . Until then: - no trigger information will be distributed via the GCN circulars; - the lightcurves and the spacecraft ephemeris data for all SPI-ACS triggers are available at the public ftp area of the ISDC: ftp://isdcarc.unige.ch/arc/FTP/ibas/spiacs - a summary list of SPI-ACS triggers summarizing only those triggers with (probable) burst origin can be found at: http://www.mpe.mpg.de/gamma/instruments/integral/spi/acs/grb/tab.html A new GCN circular will inform about the procedure after switch on of the automatic GRB alert generation for the SPI-ACS data.
