We report on analysis of the two-color VR CCD observations of the newlydiscovered variable 2MASS J18024395+4003309=VSX J180243.9+400331 obtained usingthe 1-m telescope of the Mt. Lemmon Observatory (LOAO) in the field of theintermediate polar V1323 Her. The extended version of this conference talk wepublished in 2015JASS...32..127A. The variability was reported in2012OAP....25..150A, and the object was monitored. The two-color observationscovered all phase interval. The object is classified as an Algol-type variablewith tidally distorted components, and shows an asymmetry of the maxima (theO\'Connell effect). For phenomenological modeling, we used the trigonometricpolynomial approximation of statistically optimal degree, and a recent method"NAV" (New Algol Variable) using local specific shapes for the eclipse.Methodological aspects are described, especially for the case of few colorobservations. Estimates of the physical parameters based on analysis ofphenomenological parameters, are presented.
