Notes
Probably noise or an instrument effect.
Found automatically by hunt.py in TESS sector 15 (flagged in 3 sector(s)). Detection score 165.4.
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.
