Soulier J.-F. (Observatoire de Maisoncelles) reports
the observation of the afterglow of GRB 120326A
19.7 hours after the GRB using a 30cm F/4 telescope
at the Observatoire de Maisoncelles, France (IAU
observatory code is C10).

A CCD camera ST7XME and no filter were
used. A stack of images shows clearly the
presence of the afterglow that confirms the
rebrightening mentioned by Gorosabel et al.
(GCNC 13112):
