        MOA 2006-BLG-003: Possible caustic entry


Dear Colleagues,

data collected by PLANET with the Canopus 1 m
telescope at Hobart, Tasmania (Australia) reveal an anomalous behaviour
of event MOA 2006-BLG-003. At the beginning of the night, the event
appeared 0.5 mag brighter than predicted for that epoch, and has in the
following hours risen another 0.8 mag.
Although the data has been taken with measured seeing between 2.6" and
3.4", the rise does seems selfconsistent and real.

At this stage, the nature of the event is not clear, but a caustic entry
scenario in a binary/planetary lensing event appears to be the most likely
interpretion.

In order to find out, further dense monitoring is required and encouraged.

A light curve plot as well as data will appear on our webpages soon.

Event:           MOA 2006-BLG-003
RA (J2000):      17:55:22.32
Dec (J2000):     -33:04: 8.8

The baseline I magnitude reported by the MOA team is 17.11.
