# Pre-registered predictions: TIC 65043946, TESS Sector 111
Written 2026-10-09 by TRENCHPLANET Project, before Sector 111 data exist.

- Ephemeris: P = 7.7734904 ± 0.0000126 d, T0 = BJD_TDB 2459245.93924 ± 0.00162
- Depth 1570 ± 145 ppm, duration 1.69 h

| Predicted mid-transit (UTC) | BJD_TDB | 1σ |
|---|---|---|
| 2026-12-01 08:59 | 2461375.8756 | ± 5 min |
| 2026-12-09 03:33 | 2461383.6491 | ± 6 min |

Method: Detrend each sector with a 1.0 d biweight filter (wotan), fold on the fixed ephemeris above, fit only the depth of the fixed-shape trapezoid; measure the depth at phase 0.5 the same way.

- **SUPPORTED**: Sector 111 depth > 3 sigma above zero AND within 2 sigma of 1570 ppm (combined sigma ~345 ppm), no >3 sigma dip at phase 0.5.
- **REFUTED**: Sector 111 depth below 537 ppm (3 sigma under the prediction), OR a >3 sigma dip at phase 0.5, OR a difference-image / SPOC DV centroid that excludes the target at >3 sigma.
- **INCONCLUSIVE**: Anything else, including fewer than 2 of the 3 predicted transits falling in usable data.
