NICER observation list: Target ID 859805

Magnetars are young highly-magnetized isolated neutron stars with bright X-ray emission. The decay of their magnetic fields fuels their high energy radiation. Here, we propose a yearly monitoring program of six magnetars to establish their spectral and timing properties. Such a campaign will discover new spin-up and spin-down glitches, reveal their relative strengths and recovery times, and uncover new outburst and bursting epochs. Such observational results are crucial to guide the development of the crust theory in the regime of super-strong B-fields, and its link to magnetospheric physics which dictate the connection between all of the above phenomena. It is also the only mean by which we build up an unbiased sample of glitches therby moving towards a population level investigation.
