Balmer decrements for DENIS 1048-3956 compared to the M dwarf sample from MA11, the active M dwarf templates from Bochanski et al. (2007), the Sun from Johns-Krull et al. (1997), and the UCDs vB 10 (Berger et al. 2008) and LHS 2065 (Martín & Ardila 2001). The latter two objects are plotted with a small horizontal offset for clarity, and we distinguish their flare phase (star symbols) from the quiescent state. Similarly, for the Sun the range observed during a large flare is shown as a shaded area where the late flare phase is highlighted by a thin dotted line, while the quiet Sun decrements are connected by a dashed line.
