  Eight planetary nebulae have been identified as `born-again', a class of
object typified by knotty secondary ejecta having low masses ($\sim$$10^{-4}$
M$_{\odot}$) with nearly no hydrogen. Abell 30, the archetype of the class,
also belongs to a small subset of planetary nebulae that exhibit extreme
abundance discrepancy factors (where Abell 30 is the most extreme), a
phenomenon strongly linked to binary star interactions. We report the presence
of light curve brightness variations having a period of 1.060 days that are
highly suggestive of a binary central star in Abell 30. If confirmed, this
detection supports the proposed link between binary central stars and extreme
abundance discrepancies.
