We present an analysis of the microlensing event OGLE-2015-BLG-0232 .
This event is challenging to characterize for two reasons .
First , the light curve is not well sampled during the caustic crossing due to the proximity of the full Moon impacting the photometry quality .
Moreover , the source brightness is difficult to estimate because this event is blended with a nearby K dwarf star .
We found that the light curve deviations are likely due to a close brown dwarf companion ( i.e. , s = 0.55 and q = 0.06 ) , but the exact nature of the lens is still unknown .
We finally discuss the potential of follow-up observations to estimate the lens mass and distance in the future .
