  K2, the two-wheel mission of the Kepler space telescope, observed the
pulsating subdwarf B star EQ Psc during engineering tests in 2014 February. In
addition to a rich spectrum of g-mode pulsation frequencies, the observations
demonstrate a light variation with a period of 19.2 h and a full amplitude of
2%. We suggest that this is due to reflection from a cool companion, making
EQ\,Psc the longest-period member of some 30 binaries comprising a hot subdwarf
and a cool dwarf companion (sdB+dM), and hence useful for exploring the
common-envelope ejection mechanism in low-mass binaries.
