epsilon Aurigae 2009-2011 eclipse observations

An overview of our ongoing photometric and spectroscopic monitoring of the \varepsilon Aurigae eclipse in 2009-2011 is presented. The obtained until now observational data is described and discussed. The changes in the spectrum, which can be attributed to the eclipsing disk, are illustrated with the variations in the profiles and the equivalent widths of selected spectral features. The mean radial velocities measured in our spectra are compared with a recent spectroscopic orbital solution. The duration of eclipses is also discussed briefly.
