KOI2904 This system hosts a 1.2 Rearth planet with a 16.4 day period (Burke et KOI2014a
al 2014). We detected a companion 2.74 J mags and 2.58 Ks mags fainter
than KOI2904 at a separation of 0".68. Using the J-Ks to Kp-Ks color-
color conversion from Howell et al. (2012), we predict that the Kp mag KOI2012a
of the companion is Kp = 15.8 (dKp = 3.1) if the star is a dwarf or
Kp = 15.9 (dKp = 3.2) if the star is a giant. KOI 2904 has also been
observed with speckle imaging using DSSI on WIYN and the companion was
detected with mag differences of 2.83 mag at 692 nm and 2.77 mag at
880 nm. The estimated dilution correction for this system is 3%
assuming that the planet orbits the target star and that all of the
light from the companion is captured in the Kepler aperture. KOI2904
does not display a significant source offset during transit. Dre2014
