Topic: 1 Session: poster Abstract: We present optical photometric and spectroscopic observations of the nucleus of NGC 4395, as part of a multiwavelength reverberation-mapping program. We detect significant continuum variability and interband cross-correlation lags between simultaneous optical/UV and optical/X-ray light curves. We also find suggestive evidence of a Balmer emission-line lag, yielding a black hole mass measurement which is consistent with the value derived from the simultaneous UV data.
