Title: OGLE-BLG182.1.162852: An Eclipsing Binary with a Circumstellar Disk
Author: N. J. Rattenbury, L. Wyrzykowski, Z. Kostrzewa-Rutkowska, A. Udalski, S. Kozlowski, M. K. Szymanski, G. Pietrzynski, I. Soszynski, R. Poleski, K. Ulaczyk, J. Skowron, P. Pietrukowicz, P. Mróz, D. Skowron

We present the discovery of a plausible disk-eclipse system OGLE-BLG182.1.162852. The OGLE light curve for OGLE-BLG182.1.162852 shows three episodes of dimming by I \simeq 2-3 magnitudes, separated by 1277 days. The shape of the light curve during dimming events is very similar to that of known disk eclipse system OGLE-LMC-ECL-11893 (Dong et al. 2014). The event is presently undergoing a dimming event, predicted to end on December 30th, 2014. We encourage spectroscopic and multi-band photometric observations now. The next dimming episode for OGLE-BLG182.1.162852 is expected to occur in March 2018.
