--------------------------------------------- PLANET ANOMALY ALERT 2006 #14 (issued 17-Aug, 7:00 UT) --------------------------------------------- Smooth rise in OGLE 2006-BLG-450 Dear Colleagues, while OGLE 2006-BLG-450 was considered falling after a maximum near HJD=2453962.7 (15-Aug, 5:00 UT), PLANET data collected with the SAAO 1.0m (Sutherland, South Africa) after HJD=2453964.337 (16-Aug, 20:05 UT) showed a brightening by 0.1 mag, indicating a smooth rise after HJD=2453963.7 (16-Aug, 5:00 UT). Further data collected with the Danish 1.54m at ESO LaSilla (Chile) reveal a continuation of this rise with increasing slope, which tends to become constant in the most recent data until HJD=2453964.724 (17-Aug, 5:22 UT). The observed rise is consistent with that reported by OGLE a few hours ago. Provided that a caustic entry occured near HJD=2453957.0 (9-Aug, 12:00 UT), we might see the corresponding caustic exit. However, with the current data, models without caustic passages seem possible. Immediate further observations are strongly encouraged in order to determine the shape of the approached peak, which will provide a strong clue to the nature of this event. A light curve plot as well as data are available on our webpages. Event: OGLE 2006-BLG-450 RA (J2000): 17:52:00.47 Dec (J2000): -31:07:36.3 The baseline I magnitude reported by the OGLE team is 18.869 +/- 0.003.
