  OGLE 2006-BLG-277 brightened by 1.7 mag during fold-caustic entry
                     and is approaching plateau

Dear Colleagues,

further PLANET data collected on OGLE 2006-BLG-277 with the Perth 0.6m
(Bickley, Western Australia) and the Danish 1.54m at ESO LaSilla (Chile)
show that the source entered the caustic already at HJD=2453932.78 +/- 0.01
(16-Jul, 6:45 UT +/- 15 min), after which a brightening by about 1.7 mag
until the reported caustic peak was reached. Both data sets now show the
flattening towards a plateau region, roughly 1 mag above the pre-entry
level, which separates two fold-caustic passages. The strong brightening
strongly disfavours a planetary origin.

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