------------------------------------------------ PLANET TEAM ANOMALY UPDATE FOR OGLE-2000-BUL-38 ------------------------------------------------ The PLANET collaboration has been monitoring the multiple-lens microlensing event OGLE-2000-BUL-38 intensively since it was first announced as an anomalous event by the OGLE team. According to the OGLE data, this event executed a first caustic crossing just before Heliocentric Julian Date (HJD)=2451707. Since then, the source light curve has declined and levelled out in the caustic trough. We recently reported that the light curve of the soure had risen from this trough, presumably on its way to a second caustic crossing. An OGLE announcement earlier today confirmed this trend. Here we report that our most recent PLANET data indicate a rise of about 0.23 magnitudes in the last 24 hours. These data are suggestive of a caustic crossing occuring soon, perhaps as soon as HJD = 2451739.4, although we are awaiting more data before we can make a firm prediction. Photometric and spectroscopic monitoring of caustic crossings can provide unique information, since the atmosphere of the source star is resolved spatially by the caustic. Event: OGLE-2000-BUL-38 RA (J2000): 17:53:19.20 Dec (J2000): -29:57:33.9 The baseline I magnitude reported by the OGLE team is 17.87. PLANET continues to observe this event.
