Abstract
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 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.
