  We report observations of a remarkable major axes alignment nearly parallel
to the Galactic plane of 5{\sigma} significance for a subset of bulge
"planetary nebulae" (PNe) that host, or are inferred to host, short period
binaries. Nearly all are bipolar. It is solely this specific PNe population
that accounts for the much weaker statistical alignments previously reported
for the more general bulge PNe. It is clear evidence of a persistent, organised
process acting on a measurable parameter at the heart of our Galaxy over
perhaps cosmologically significant periods of time for this very particular PNe
sample. Stable magnetic fields are currently the only plausible mechanism that
could affect multiple binary star orbits as revealed by the observed major axes
orientations of their eventual PNe. Examples are fed into the current bulge
planetary nebulae population at a rate determined by their formation history
and mass range of their binary stellar progenitors.
