We present new observations leading to an improved black hole mass estimatefor the Seyfert 1 galaxy NGC 4593 as part of a reverberation-mapping campaignconducted at the MDM Observatory. Cross-correlation analysis of the H_betaemission-line light curve with the optical continuum light curve reveals anemission-line time delay of 3.73 (+-0.75) days. By combining this time delaywith the H_beta line width, we derive a central black hole mass of M_BH =9.8(+-2.1)x10^6 M_sun, an improvement in precision of a factor of several overpast results.
