We present the results of multifrequency monitoring of the Seyfert galaxy Mkn 421 in optical (R band) and TeV frequencies. The optical data were taken over approximately four months at the Sommers-Bausch Observatory (U. Colorado-Boulder), and at Boltwood Observatory in Canada. The TeV data were taken as part of the HEGRA collaboration. Routine analysis of the microvariability data taken in the optical allows us to determine the maximum size and mass of the emitting region, and Eddington luminosity. We also investigate the spectral changes over the optical-TeV range. We believe we see a correlation between the bright and dim phases of the optical and TeV data, respectively. This could include a lag period between the two brightness increases, and of course it also indicates emission from the same region. To do a proper cross-correlation frequency study one would require more data both in optical and in the TeV. Any subsequent project involving the observation of Mkn 421 will require a denser data set.
