The orbital period is P${\\sim}2.57$ years and the primary eclipse lasts ${\\sim}73$ days. The eclipse profile is suggestive of a disk eclipsing binary rather than a stellar component. We also detect ${\\sim}0.4$ mag pulsations with a period of P${\\sim78}$ d. The next eclipse begins on September, 28, 2018. Further photometric and spectroscopic observations are encouraged, particularly when the system is in eclipse.","authors_text":"B. J. Shappee, C. S. Kochanek, J. L. Prieto, K. Z. Stanek, M.
