Superflares on giant stars have up to 100,000 times more energy than the high energy
solar flares. However, it is disputed, whether scaling up a solar-type dynamo could
explain such a magnitude difference. We investigate the flaring activity of KIC 2852961,
a late-type spotted giant. We seek for flares in the Kepler Q0-Q17 datasets by an
automated technique together with visual inspection. Flare occurence rate and flare
energies are analyzed and compared to flare statistics of different targets with similar
flare activity at different energy levels. We find that the flare energy distribution
of KIC 2852961 does not seem to be consistent with that of superflares on solar-type
stars. Also, we believe that in case of KIC 2852961 spot activity should have an important
role in producing such superflares.
