The measured bursts lasted an average of 100 milliseconds but ranged from 25 ms to 1.8 seconds.
[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.
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.
