We studied the accretion disc structure in the doubly imaged lensed quasar SDSS J1339+1310 usingr-band light curves and UV-visible to near-IR spectra from the first 11 observational seasons after its discovery. The 2009−2019 light curves displayed pronounced microlensing variations on different timescales, and this microlensing signal permitted us to constrain the half-light radius of the 1930 Å continuum-emitting region. Assuming an accretion disc with an axis inclined at 60° to the line of sight, we obtained . We also estimated the central black hole mass from spectroscopic data. The width of the C IV, Mg II, and Hβemission lines, and the continuum luminosity at 1350, 3000, and 5100 Å, led to log(MBH/M⊙) = 8.6 ± 0.4. Thus, hot gas responsible for the 1930 Å continuum emission is likely orbiting a 4.0 × 108M⊙black hole at anr1/2of only a few tens of Schwarzschild radii.
