On the night of March 4/5, 2010
the OGLE project resumed regular
observations
at Las Campanas Observatory and entered its fourth phase -
OGLE-IV.
With the new 32 chip mosaic camera the observing capabilities
of OGLE increased by almost order of magnitude compared to OGLE-III
phase.
Standard OGLE services will be gradually restored when the real
time data reduction pipeline is re-implemented at the telescope.
