KOI2298 This system contains a 1 Rearth planet candidate with a 16.7 day orbit
(Batalha et al. 2013). NEXSci also reports a 0.8 Rearth false positive KOI2013a
with a 31.8 day period. We detected a companion 1.3 Ks mags fainter
than KOI2298 at a distance of 1".47. The companion is expected to have
Kp = 15.2 (dKp = 1.4), indicating that contamination may lead to a
significant underestimate of the planet radius. In the simple
approximation that all light from the companion star is captured in
the Kepler aperture, the radius estimate for the planet should be
increased by 13% to account for the dilution if indeed the planet
orbits the target star and the companion has Kp = 14.9. However, the
companion may be the same object identified ~1" away from KOI2298 in a
HIRES guider image. The estimated brightness contrast from the HIRES
image is three mags, which implies companion is red enough that the
dilution correction might be only a 3% change to the planet radius Dre2014
