The halo formed as X-rays from the brightest flares scattered off of intervening dust clouds. The animation shows the glow of the halo pulsing and dispersing over six days in January 2009. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Swift-Soft-Gamma-Ray-Repeater-10366-date-overlay/Swift-Soft-Gamma-Ray_Repeater-10366-date-overlay.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
