It has been observed by the Swift satellite, and by the Fermi Gamma-ray Space Telescope, launched in 2008, as well as in X-ray and radio emission.
[1][2] It has been observed to emit intense bursts of gamma rays at a rate of up to several per minute.
At its estimated distance of 30,000 light years (~10 kpc), the most intense flares equal the total energy emission of the Sun in ~20 years.
[3] The underlying object is believed to be a rotating neutron star, of the type known as magnetars, which have magnetic fields up to 1015 gauss, about 1000 times that of more typical neutron star X-ray sources.
The location of SGR J1550−5418 (aka AXP 1E 1547.0-5408),[4] is RA(J2000) = 15h50m54.11s, Dec(J2000) = −54°18'23.7".
