Abstract
We present our observations of the low-mass eclipsing binary GJ 3236. We have analyzed a phased \(R_{C}\) light-curve and confirmed previously determined fundamental parameters of the components. We detected evolution of the spot(s) and found that there exists a large spot near a polar region of the primary component and another spot either on the primary or the secondary component. We also observed 7 flare events and determined a flare rate of about 0.1 flares per hour. We observed two high energy, long-term flares with a complex light curve and possibly four weak short-term flaring events. A majority of the flares was detected in the \(R_{C}\) filter, which indicate their high energy.
