The 847 keV line due to the radio-active decay of Co56 from the Type Ia Supernova SN2014J in M82 (CBET #3792) has been detected by INTEGRAL. The observations (public data and proposal 1170002, PI: R. Sunyaev; e.g., ATel #5835) took place between UT March 3rd and March 19th, 2014, corresponding to days ~46-63 after the explosion (assuming that explosion took place on Jan 15th, Zheng et al. 2014, ApJ 783, L24) .
