Query: The Precession Caused by Gravitational Waves   We show that gravitational waves cause freely falling gyroscopes to precess
relative to fixed distant stars, extending the stationary Lense-Thirring
effect. The precession rate decays as the square of the inverse distance to the
source, and is proportional to a suitable Noether current for dual asymptotic
symmetries at null infinity. Integrating the rate over time yields a net
rotation -- a `gyroscopic memory' -- whose angle reproduces the known spin
memory effect but also contains an extra contribution due to the generator of
gravitational electric-magnetic duality. The angle's order of magnitude for the
first LIGO signal is estimated to be $\Phi\sim 10^{-35}$ arcseconds near Earth,
but the effect may be substantially larger for supermassive black hole mergers.
