Notes

WARNING: same period as the known variable ASASSN-V J191047.11+501930.0 37" away; the signal is probably its light leaking in. Found automatically by hunt.py in TESS sector 15 (flagged in 1 sector(s)). Detection score 1383.7. 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.
