N2 - Recently, Zheng et al. (2006) found evidence for an overdensity of galaxies around a radio-loud quasar, SDSS J0836 + 0054, at z = 5.8 (a 5 arcmin 2 field). We examined our deep optical imaging data (B, V, r′, i′, z′, and NB816) taken with the Suprime-Cam on the Subaru Telescope. The NB816 narrow-band filter (λc = 815 nm and Δλ. = 12nm) is suitable to search for Lyα emitters at z ≈ 5.7. We found a new strong Lyα emitter at z ≈ 5.7 close to object B, identified by Zheng et al. (2006). Further, the non-detection of nine objects selected by Zheng et al. (2006) in our B, V, and r′ images provides corroborative evidence to indicate that they are high-z objects.
