--------------------------------------------- PLANET ANOMALY ALERT 2006 #6 (issued 29-Jun, 12:50 UT) --------------------------------------------- Suspected planetary deviation in OGLE 2006-BLG-335 Dear Colleagues, PLANET data collected with the Canopus 1.0m (near Hobart, Tasmania) and the Danish 1.54m at ESO LaSilla (Chile) after HJD=2453914.98 (28-Jun, 11:30 UT) seem to deviate from a model light curve through the previous points assuming a single lens and a point-like source star. Similar behaviour in the OGLE data has previously been reported by the OGLE team. Trying to revise the model to account for all data leaves us with a small deviation for earlier epochs as well as unreasonable blend ratios. While OGLE 2006-BLG-335 poses a challenge for obtaining a reliable light curve, it does not appear unlikely that we observe a short 10-15% deviation lasting about 1.5 days, which now approaches its end. Most recent data from the Canopus 1.0m, from HJD=2453915.95 (29-Jun, 10:45 UT) onwards, confirm this trend. The significance for the anomaly will increase with further data being collected, which will better constrain the (background) single-lens model and in particular the blend ratio. In order to characterize the anomaly, very frequent monitoring over at least the next 12 hours is recommended. A light curve plot as well as data is available on our webpages. Event: OGLE 2006-BLG-335 RA (J2000): 17:52:19.15 Dec (J2000): -30:39:39.6 The baseline I magnitude reported by the OGLE team is 18.746 +/- 0.003.
