  We present the analysis of 4 months of Kepler photometry of the K4V star
HAT-P-11, including 26 transits of its "super-Neptune" planet. The transit data
exhibit numerous anomalies that we interpret as passages of the planet over
dark starspots. These spot-crossing anomalies preferentially occur at two
specific phases of the transit. These phases can be understood as the
intersection points between the transit chord and the active latitudes of the
host star, where starspots are most abundant. Based on the measured
characteristics of spot-crossing anomalies, and previous observations of the
Rossiter-McLaughlin effect, we find two solutions for the stellar obliquity
(psi) and active latitude (l): either psi = 106 and l = 19.7, or psi = 97 and l
= 67 (all in degrees). If the active latitude changes with time in analogy with
the "butterfly diagram" of the Sun's activity cycle, future observations should
reveal changes in the preferred phases of spot-crossing anomalies.
