We propose to observe a bright nearby ULX NGC 4190 ULX-1 using twoquasisimultaneous NuSTAR and XMM-Newton exposures of 50ks and 35ks perobservation respectively. Its persistently high flux (>10^-12 erg/s/cm^2) andvariable spectral behaviour at high X-ray energies make NGC 4190 ULX-1 aparticularly accessible and interesting object of study. While pulsations havenot previously been detected the narrow profile of its hot thermal componentand its luminosity-temperature relation suggest the presence of asuper-Eddington disk truncated by a strong magnetic field. Multiple broadbandobservations are required to populate its luminosity-temperature relationestimate a magnetic field strength and search for pulsations which would be the smoking guna?? indicating a neutron star accretor.
