The 5.5 years periodicity of eta Carinae is manifested in the ``events'' observed in different wavelength 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 Hα filter set. The light curves and photometric data collected during the second half of our 2009 observing season are presented in this paper.
