Long considered a typical source of gamma radiation , SGR J1550-5418 attracted the attention of astronomers as a manifestation of activity on October 23, 2008 . The intensity of gamma-ray bursts increased, especially strong activity was registered on January 22, 2009 . The object was the subject of research of the Swift orbital telescope [3] . So, it turned out that the gamma repeater produces several flashes per minute, the most powerful of which carry energy equivalent to that of the Sun , produced in 20 years . According to its characteristics, SGR J1550-5418 is a neutron star , or rather its kind - magnetar .
