Observations of the star EPIC 220208795 (2MASS J01105556+0018507) reveal asingle, deep and asymmetric eclipse, which we hypothesize is due to aneclipsing companion surrounded by a tilted and inclined opaque disk, similar tothose seen around V928 Tau and EPIC 204376071. We aim to derive physicalparameters of the disk and orbital parameters for the companion around theprimary star. The modeling is carried out using a modified version of thepython package pyPplusS, and optimization is done using emcee. The periodanalysis makes use of photometry from ground-based surveys, where we perform aperiod folding search for other possible eclipses by the disk. Parametersobtained by the best model fits are used to obtain the parameter space of theorbital parameters, while the most likely period obtained is used to constrainthese parameters. The best model has an opaque disk with a radius of$1.14\pm0.03$ $R_{\odot}$, an impact parameter of $0.61\pm0.02$ $R_{\odot}$, aninclination of $77.01^{\circ}\pm0.03^{\circ}$, a tilt of$36.81^{\circ}\pm0.05^{\circ}$ and a transverse velocity of $77.45\pm0.05$ kms$^{-1}$. The two most likely periods are $\sim 290$ days and $\sim 236$ days,corresponding to an eccentricity of $\sim 0.7$, allowing us to make predictionsfor the epochs of the next eclipses. All models with tilted and inclined disksresult in a minimum derived eccentricity of 0.3, which in combination with thetwo other known small transiting disk candidates V928 Tau and EPIC 204376071,suggest that there may be a common origin for their eccentric orbits.
