Abstract:The results of three short photometric monitoring runs on the L0 dwarf 2MASS J06050196−2342270, during three consecutive nights, are presented. The observations show the persistent presence of a 2.4-h period, with an   IC   band amplitude which decreased from 27 to 11 mmag over the three nights. The amplitude in the   RC   band appeared to be substantially smaller than in the   IC   band.
Keywords:stars: low mass  brown dwarfs  stars: variables: other
