  We explore the properties of an optical transient event formed by the
destruction of a planet by a brown dwarf (BD) -- a BD-planet mergerburst. When
a massive planet approaches a BD towards a merging process it will be tidally
destroyed and will form an accretion disk around the BD. The viscosity in the
disk sets the characteristic time for the event -- several days. We suggest
that BD-planet mergerburst events have light curves resembling those of other
intermediate luminosity optical transient (ILOT) events, such as V838 Mon, but
at shorter timescales and lower luminosities. With the high percentage coverage
of the sky, we expect that such events will be detected in the near future.
