TESS FFI eleanor lightcurve of the 2+2 quadruple candidate TIC 165052445. A resolved nearby star (separation of about 3﹩\mathop{.}\limits^{\unicode{x02033}}﹩8), TIC 741891699, has similar parallax and proper motion to the target, suggesting the two may be a potentially comoving wide quintuple. The apparent depth changes in both sets of eclipses are systematic in nature, due to contamination from TIC 165052447 (∼3 pixels away and ∼2 mag brighter).
