Time-series observations of the ultracool dwarf SSSPM J0109 - 5101
Abstract
The results of five nights of photometric monitoring of SSSPM J0109-5101 are presented. Observations in the IC band show a probable periodicity of 7.8 h, with an amplitude of 19 mmag. The results of 5 h of measurements in the R band are particularly interesting, showing several flares.
