--------------------------------------------- PLANET ANOMALY UPDATE 2005 #7-3 (issued 9-Jul, 12:15 UT) --------------------------------------------- On the decrease from exit peak and leaving caustic in about 18 hrs Dear Colleagues, continued monitoring of OGLE 2005-BLG-153 / MOA 2005-BLG-23 by PLANET with the Danish 1.54m at ESO LaSilla, the Perth 0.6m near Bickley (Western Australia) and the Canopus 1.0m near Hobart (Tasmania) as well as OGLE data show that the event has passed the anticipated caustic exit peak near HJD=2453560.4 (8-Jul, 21:30 UT) and is expected to leave to caustic at HJD=2453561.72 +/- 0.03 (10-Jul, 5:15 UT) after the source needed (1.63 +/- 0.03) days for crossing it. For a good measurement of the brightness profile of the source star, it is essential to accurately determine the epoch of the caustic exit. Dense measurements around that region, near which moreover a strong signal of stellar limb darkening can be expected, are therefore strongly encouraged. A light curve plot and data files for this event are available on our webpage, which is frequently updated. Event: OGLE 2005-BLG-153 / MOA 2005-BLG-23 RA (J2000): 18:04:17.30 Dec (J2000): -28:40:49.3 The baseline I magnitude reported by the OGLE team is 13.953.
