We derive the spectrum from five transits observed between 2016 and 2018, with combined wavelength coverage between 5200 {\\AA} - 9269 {\\AA} in 200 {\\AA} bins, and with a median precision of 247 ppm per bin. HAT-P-23b's relatively high surface gravity (g ~ 30 m/s^2), combined with updated stellar and planetary parameters from Gaia DR2, gives a 5-scale-height signal of 384 ppm for a hydrogen-dominated atmosphere.
