We report the following transient found by the ATLAS survey (see Tonry et al. ATel #8680). ATLAS is a twin 0.5m telescope system on Haleakala and Mauna Loa. The first unit is operational on Haleakala is robotically surveying the sky. Two filters are used, cyan and orange (denoted c and o, all mags in AB system), more information is on http://www.fallingstar.com. All transients have been registered with the IAU.
Host galaxy identifications and redshifts are from NED or the Pan-STARRS1 3Pi image stack, and absolute magnitude calculations include an estimate of Milky Way foreground extinction at the filter wavelength.

1. NED reports that the likely host (8.28 arcsec away) is 2MASX J15271348+2845573 with spectroscopic redshift z=0.061936, hence mu=37.14, A_o=0.05, M_o=-18.55.
