We report the analysis of time-series of optical photometry of SDSS J0926+3624 collected with the Liverpool Robotic Telescope between 2012 February and March while the object was in quiescence .
We combined our median eclipse timing with those in the literature to revise the ephemeris and confirm that the binary period is increasing at a rate \dot { P } = ( 3.2 \pm 0.4 ) \times 10 ^ { -13 } s / s .
The light curves show no evidence of either the orbital hump produced by a bright spot at disc rim or of superhumps ; the average out-of-eclipse brightness level is consistently lower than previously reported .
The eclipse map from the average light curve shows a hot white dwarf surrounded by a faint , cool accretion disc plus enhanced emission along the gas stream trajectory beyond the impact point at the outer disc rim , suggesting the occurrence of gas stream overflow/penetration at that epoch .
We estimate a disc mass input rate of \dot { M } = ( 9 \pm 1 ) \times 10 ^ { -12 } M _ { \odot } yr ^ { -1 } , more than an order of magnitude lower than that expected from binary evolution with conservative mass transfer .
