  We present results from 2 years of monitoring of Huchra's lens (QSO
2237+0305) with the 1.3 m Warsaw telescope on Las Campanas, Chile. Photometry
in the V band was done using a newly developed method for image subtraction.
Reliable subtraction without Fourier division removes all complexities
associated with the presence of a bright lensing galaxy. With positions of
lensed images adopted from HST measurements it is relatively easy to fit the
variable part of the flux in this system, as opposed to modeling of the
underlying galaxy. For the first time we observed smooth light variation over a
period of a few months, which can be naturally attributed to microlensing. We
also describe automated software capable of real time analysis of the images of
QSO 2237+0305. It is expected that starting from the next observing season in
1999 an alert system will be implemented for high amplification events (HAE) in
this object. Time sampling and photometric accuracy achieved should be
sufficient for early detection of caustic crossings.
