A new ULX in the galaxy NGC 4045 that reaches X-ray luminosities greater than 10elev41 erg selev-1 was recently found comma making it one of the most powerful ULXs discovered to date. DDT observations with NuSTAR revealed enticing candidate signals of an absorption line at 8.7 keV which could be the signature of an ultrafast outflow comma the hallmark of super-Eddington accretion comma and a potential pulsation signal comma that could confirm the source as an neutron star accretor. However comma neither of these were found to be significant in the 50-ks observation. Here we propose follow-up target of opportunity observations with NuSTAR and XMM-Newton in order to confirm these signals.
