TIC 308184057.01: a candidate warm sub-Saturn transiting a faint K dwarf, found in a TESS full-frame-image search of stars below the QLP magnitude limit

Preprint, data products and analysis code for the transiting planet candidate TIC 308184057.01, found in an independent search of TESS full-frame-image light curves of stars fainter than the QLP magnitude limit. P = 6.1190153 ± 0.0000064 d, depth ≈ 1.1% (Rp/R★ = 0.106 ± 0.003, Rp ≈ 0.76 R_J), T14 = 2.40 h. The signal is present in 17 TESS sectors (2018–2025), odd/even consistent, with no secondary eclipse. Difference imaging places it on target, and Gaia DR3 RUWE is 0.95. TRICERATOPS FPP = 0.19. This is a candidate only: it is not peer reviewed and not validated or confirmed. Ground-based photometry, high-resolution imaging and radial velocities are requested; see the ephemeris inside.
