SGR 1627−41, is a soft gamma repeater (SGR), located in the constellation of Ara. It was discovered June 15, 1998 using the Burst and transient Source Experiment ( BATSE) and was the first soft gamma repeater to be discovered since 1979. During a period of 6 weeks, the star bursted approximately 100 times, and then went quiet. The measured bursts lasted an average of 100 milliseconds, but ranged from 25 ms to 1.8 seconds. SGR 1627−41 is a persistent X-ray source. ^[1] It is located at a distance of 11  kpc in the radio complex CTB 33, a star forming region that includes the supernova remnant G337.0-0.1. ^[2]

This object is believed to be a neutron star that undergoes random outbursts of hard and soft X-rays. This may be caused by the loss of angular momentum of a highly magnetized neutron star, or magnetar. Alternatively, it may be a quark star, although this is considered less likely. After the 1998 outburst and the 40-day afterglow, SGR 1627−41 has remained dormant and is steadily cooling down from the peak during the event. ^{[3] [4]}
