A fit with a fixed shape and period finds the WASP-47 d transit signal in three 2025 TESS windows

Public TESS data from May 2025 contain three expected transit windows for WASP-47 d. We test these windows with the published period of 9.030501 days and a fixed transit shape. A fit with a common depth gives a central flux loss of 1049 parts per million, with a conditional error of 153 parts per million. It improves chi-square by 47.0 over separate baselines without a transit. The common offset is 13.1 minutes after the 2023 mean prediction. The formal profile and block noise tests give interval limits of 5.2 and 23.8 minutes. The 95 percent block range is -10.2 to 37.7 minutes. None of 4000 noise-only trials for each of three block lengths matches the signal after the full timing search. The signal remains in simple aperture flux and under changes to the baseline and masks. These choices give depths from 917 to 1294 parts per million. We also release five 2025 transit centers for WASP-47 b. The package preserves the source light curves, code, provenance, results, and figures. A five percent reduction in the assumed orbit size relative to the star moves the best offset to -0.4 minute. The timing intervals therefore depend on the fixed shape. These data add a later phase measurement. They do not establish a new period or resolve the known dynamical timing changes.
