Checked 2026-10-11 16:26 on NVIDIA GeForce RTX 4070, using every TESS sector of this star. All results (.json)

Notes

Probably noise or an instrument effect. WARNING: same period as the known variable ASASSN-V J173822.91+775451.3 45" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 19 (flagged in 13 sector(s)). Detection score 333.7. Not in VSX, ASAS-SN or ZTF variable catalogues at the time of the search; not in Gaia DR3's variable lists. Unchecked by hand yet: verify the period, nearby stars and a wider catalogue search. Updates: 2026-10-11 Planet check: Probably noise or an instrument effect 2026-10-09 Found by the automatic search in TESS sector 14
