	    Anomaly near expected peak in OGLE 2005-BLG-216



Dear Colleagues,

while the event OGLE 2005-BLG-216 was expected to rise to a peak to be
reached shortly, PLANET data collected with the Danish 1.54m at ESO LaSilla
between HJD=2453512.6573 (22-May, 3:46 UT) and HJD=2453512.8364 (22-May,
8:04 UT) show a decrease by about 0.15 mag that is incompatible with models
assuming point-like sources and lenses. The OGLE collaboration suggests that
the event is substantially blended, pushing the source magnification at a
much larger value than the observed A ~ 10.

Since the nature of the anomaly is not clear at the moment, dense monitoring
is strongly recommended.

A light curve plot and data files for this event are available on our
webpage, which is frequently updated.

Event:           OGLE 2005-BLG-216
RA (J2000):      17:45:29.56
Dec (J2000):     -24:03:14.0

The baseline I magnitude reported by the OGLE team is 18.586 +/- 0.004.
