The 5.5 years periodicity of Eta Carinae is manifested in the "events" observed in different wavelenght ranges. The last of these "events" occurred as expected in 2009.0. Our  ground-based photometric campaign registered this "event" which showed an "eclipse-like" feature. After that, we continued the observations in order to get information about the post-event behaviour. Our monitoring program consists of daily CCD photometry, obtained using the 0.8 m "Virpi S. Niemela" telescope at La Plata Observatory, and a BVRI and Halpha filter set. The light curves and photometric data collected during the second half of our 2009 oberving season are presented in this paper.
