To help corroborate the findings of correlations between quasar variability and black hole mass, we investigated the structures and upper limits to the emitting regions of a small sample of quasars using the remotely operated 24 inch NFO Webscope near Silver City, NM. By studying the variability of the quasar magnitudes in optical wavebands, we were able to make estimates as to the radius of the central emitting region. The quasars were chosen at a range of redshifts, and observed during the summers of 2005 and 2006. The data from 2005 has been analyzed and variations in magnitude of 0.0237, -0.0385, and 0.5602 were observed in three different quasars over a period of days (Fleming & Kennefick 2005 BAAS 20714101). We have analyzed the 2006 data set of the same quasars to compare the variations with those obtained in the 2005 data, which allowed us to study variations on timescales of both days and months. Spectra of the quasars were obtained from the published literature which allowed us to derive estimates of the black hole mass using standard techniques. We additionally discuss whether the results are supportive of a variability-black hole mass relationship. Although our quasar sample is small, it is hoped our research will aid in enhancing the understanding of inter-relationships among intrinsic quasar parameters. This work was funded by an NSF REU Supplement and an Arkansas CSAPS Research Grant.
