  The EROS collaboration has developed a real time alert system, which was
operational in 1999 and 2000. A very long binary-lensing caustic crossing
event, EROS-BLG-2000-5, was found in the 2000 season and monitored by EROS.
EROS photometric data for this event are presented. The data are well fitted by
the model of An et al. 2002 based on a completely different dataset.
  However, parameters of the model such as the mass ratio or the binary
rotation rate are not very well constrained by EROS data.
