Kepler K2-C1 EPIC-202060447: Eclipsing Binary

Discussion:
This K2-observed system is known but is listed in the SIMBAD database simply as a "Star".  However, from the nature of its light curve, it is more likely a semi-detached EB of the Beta Lyrae type [minima of different depths, but not as dramatic as Algol (detached) types, and "baseline" variation outside of eclipse, but not as dramatic as W Uma (contact) types].  This is especially clear in the expanded section of the light curve (Figure 2. below).

The plotted Corrected Flux vs. Time data (converted from NASA's K2 raw data by A. Vanderburg) were accessed by starting with his website https://www.cfa.harvard.edu/~avanderb/k2.html.  RED points are the major eclipses; YELLOW points are the minor eclipses.  Baseline variation and drift means that eclipse depth values are only approximations.
