  In 1998 The Optical Gravitational Lensing Experiment (OGLE) successfully
implemented automated data reductions for QSO 2237+0305. Using a new image
subtraction method we achieved a differential photometry scatter of 1-5 % for
images A-D respectively. Combined with a time sampling of 1-2 times a week this
is sufficient for early detection of caustic crossings. Nearly real time
photometry of QSO 2237+0305 is available from the OGLE web site
http://www.astro.princeton.edu/~ogle/ogle2/huchra.html . During the 1999
observing season, the apparent V magnitude of the A, B, C and D images changed
by 0.50, 0.15, 0.65 and 0.35 mag, respectively. Most likely however, none of
the microlensing events involved a caustic crossing. The most rapid variation
was 0.25 mag in 30 days, observed for image C. The alert system will continue
to be active in the next observing season from late April until September 2000,
when OGLE suspends operation for an upgrade. Observations will resume for
season of 2001.
