Notes

WARNING: same period as the known variable NSVS 1091964 41" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 21 (flagged in 8 sector(s)). Detection score 1656.6. 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.
