determined the stellar radius, which is the same value as the used in the Validation Report). The time of mid-transit at an arbitrarily chosen reference epoch is (BJD) T$_c=2458326.0332\pm0.0015$.

### LCOGT, MKO, and SSO T17 {#subsubsec:groundphot}

We acquired ground-based time series photometric follow-up of L 168-9 and the nearby field stars as part of the TESS Follow-up Observing Program (TFOP) to attempt to rule out nearby eclipsing binaries (NEBs) in all stars that are bright enough to cause the TESS detection and that could be blended in the TESS aperture. We used the [TESS Transit Finder]{}[^9], which is a customized version of the [Tapir]{} software package [@Jensen:2013], to schedule our transit observations.

We observed one full transit simultaneously using three 1-meter telescopes at the Las Cumbres Observatory Global Telescope (LCOGT) [@Brown2013] South Africa Astronomical Observatory node on 21 September 2018 in $i'$-band. The Sinistro detectors consist of 4K$\times$4K 15-$\mu m$ pixels with an image scale of $0\farcs389$ pixel$^{-1}$, resulting in a field-of-view of $26\farcm5 \times 26\farcm5$. The images were calibrated by the standard LCOGT BANZAI pipeline.

We observed a full transit from the Mount Kent Observatory (MKO) 0.7-meter telescope near Toowoomba, Australia on 23 September 2018 in $r'$-band. The Apogee
