We utilized six different observations from SDSS spanning across six epochs with MJDs 51794, 52199, 55186, 55201, 55451, and 57278. Our analysis revealed the existence of two broad absorption systems, A and B, in both C iv and Si iv ions from all the epoch spectra. The System A1 and System A2 in C iv are typically considered as a single BAL, but in this particular source, we noticed that the EW variations and velocity shifts of the absorption lines only occurred in the higher velocity portion, which we have identified as System A1. Thus, we divided this BAL into two sub-components to conduct further analysis. System A1 displayed a visible velocity shift between its first two-epoch spectra and the remaining four-epoch spectra, along with a weakening of its EW. The maximum velocity shift value observed for each pair of epochs of System A1 is vshift t 963 km s-1, based on the MJD 52,199 and 55,451 observations
