We observed MAXI J1847-004/Swift J1845.7-0037 on 2019-10-18 using the 1-m optical telescope at the Lulin Observatory. A series of six 600-s observations was performed with the SDSS-z' band filter for 2 hours, at the reported Swift position (ATel #13219). We obtained a mean magnitude of 20.78 +/- 0.10 mag by compared with reference stars in the PS1 catalogue, while in PS1 catalogue the mean z magnitude is 21.48 +/- 0.17 mag. While the source appeared brighter in general, the brightness fluctuates at ~0.5 magnitude. We could not resolve the star(s) at the designated position (c.f. refer to ATel #13218 for the possible counterparts, also we note that the star's position from the PS1 catalogue is closer to the object B's position reported).
