Six Years of Bursts with the SPI-ACS

The anticoincidence system of the INTEGRAL spectrometer has been an essential component of the interplanetary network since launch. It has observed about 600 events which have been confirmed as either soft gamma repeaters or cosmic gamma ray bursts by other instruments in the IPN. It has also observed over 130 events which are unconfirmed, but which are almost certainly weak bursts below the thresholds of the other IPN experiments. We review the highlights of these observations, which include gamma-ray bursts, soft gamma repeaters, and one or two extragalactic giant magnetar flares
