        Source star in OGLE 2006-BLG-375 entered caustic


Dear Colleagues,

the OGLE team reported that the brightness of OGLE-2006-BLG-375 increased 
by about 1 mag as compared to the previous night. Data collected by PLANET
with the Canopus 1.0m (near Hobart, Tasmania) show a nearly flat light curve
until HJD=2453937.189 (20-Jul, 16:32 UT), while data from the Danish 1.54m
at ESO LaSilla (Chile) after HJD=2453937.645 (21-Jul, 3:29 UT) and more recent
data from the Canopus 1.0m reveal that the source star has entered a caustic
and the event now appears to flatten to a plateau region between fold-caustic
passages.  

A light curve plot as well as data are available on our webpages.

Event:           OGLE 2006-BLG-375
RA (J2000):      18:03:00.16 
Dec (J2000):     -29:15:59.0 

The baseline I magnitude reported by the OGLE team is 17.843 +/- 0.001.
