The light curve of TIC 394177355 was already flagged by the Kepler team (KOI-3156) when it was observed back in 2015. It shows a multi-eclipsing quintuple system of pulsating stars with orbital periods of 94.2, 8.65, 1.52 and 1.43 days. TESS saw this target 5 years later in Sector 15, and observed it during a triple eclipse. Check out the paper by Hełminiak et al. (2017) to find out more about this very interesting and rare system.
