Eclipsing binaryProbably known
Notes
WARNING: same period as the known variable CSS_J052740.8-093443 56" away; the signal is probably its light leaking in.

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.
