  Source in OGLE 2006-BLG-277 likely to exit caustic within 5 hrs 

Dear Colleagues,

PLANET data collected with the Canopus 1.0m (near Hobart, Tasmania) and the
Perth 0.6m (Bickley, Western Australia) reveal a caustic peak at 
HJD=2453933.17 +/- 0.01 (16-Jul, 16:05 +/ 15 min). However, so far no change  
of the sign of curvature indicating an approach to a plateau region between
fold-caustic passages has been observed. Instead, it seems more likely that
the source has touched a cusp, so that only a single caustic peak results.
If this interpretation is correct, the trailing limb of the source is expected
to exit the caustic within the next 5 hrs.

Further dense observations are encouraged.

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