We present the results of photometric reverberation mapping observations on the changing look active galactic nucleus Mrk
590 at z = 0.026. The observations were carried out from 2018 July to December using broad-band B-, R-, and narrow-band
H α and S II filters. The B band traces the continuum emission from the accretion disc, the R band encompasses both the
continuum emission from the accretion disc and the redshifted H α line from the broad-line region (BLR), the S II band contains
the redshifted H α emission and the H α band traces the continuum emission underneath the S II band. All the light curves
showed strong variation with a fractional root-mean-square variation of 0.132 ± 0.001 in the B band and 0.321 ± 0.001 in
H α line. From cross-correlation function analysis, we obtained a delayed response of H α line emission to the optical B-band
continuum emission of 21.44+1.49 −2.11 d in the rest frame of the source, corresponding to a linear size of the BLR of 0.018 pc. This
is consistent with previous estimates using H β. By combining the BLR size with the H α line full width at half-maximum of
6478 ± 240 km s−1 measured from a single-epoch spectrum obtained with the Subaru telescope, we derived a black hole mass
of 1.96+0.15 −0.21 × 108M⊙ |
