We report the detection of the secondary eclipse of HAT-P-11 b, a Neptune-sized planet orbiting an active K4 dwarf. Using all available short-cadence data of theKeplermission, we derive refined planetary ephemeris increasing their precision by more than an order of magnitude. Our simultaneous primary and secondary transit modeling results in improved transit and orbital parameters. In particular, the precise timing of the secondary eclipse allows to pin down the orbital eccentricity to 0.26459-0.00048+0.00069. The secondary eclipse depth of 6.09-1.11+1.12ppm corresponds to a 5.5σdetection and results in a geometric albedo of 0.39 ± 0.07 for HAT-P-11 b, close to Neptune’s value, which may indicate further resemblances between these two bodies. Due to the substantial orbital eccentricity, the planetary equilibrium temperature is expected to change significantly with orbital position and ought to vary between 630 K and 950 K, depending on the details of heat redistribution in the atmosphere of HAT-P-11 b.
