MAXI J1803-298 is a recently discovered transient black hole (BH) X-ray binary that went into outburst on May 1st, 2021, and was detected with MAXI/GSC onboard the ISS. NuSTAR observed MAXI J1803-298 four times during its outburst (see Table 1, Figure 1). I modeled the spectrum to see reflection features and learn about the inner accretion disk and the environment around the BH. Figure 1 and Table 1 show that the outburst started roughly on May 1st, the peak was on May 14th, and the last observation was on June 17th.
