Abstract: We present new observations leading to an improved black hole mass estimate for the Seyfert 1 galaxy NGC 4593 as part of a reverberation-mapping campaign conducted at the MDM Observatory. Cross-correlation analysis of the Hβ emission-line light curve with the optical continuum light curve reveals an emission-line time delay of τ_cent = 3.73 ± 0.75 days. By combining this time delay with the Hβ line width, we derive a central black hole mass of MBH = (9.8 ± 2.1) × 10^6 Msun, an improvement in precision of a factor of several over past results.
