Scientific paper

The results of more than 100 h of CCD photometric monitoring of 10 L dwarfs and two T dwarfs are presented. Reasonable evidence is shown for IC band variability in DENIS 0255-4700, DENIS 1705-0516 and 2M 2104-1037. Substantial brightening of the T dwarf binary ɛ Indi Bab was observed over the course of 3.6 h; it is unlikely that this could have been caused by surface spots. No unequivocal variability could be detected in the RC band.
