report on behalf of a larger collaboration:
We observed the optical afterglow of GRB061110 (GCNs 5797, 5798) on Nov.
10 UT 19:35 (7.9h after the burst) with ALFOSC at the Nordic Optical
Telescope on La Palma in the R and i bands.
We determined magnitudes of R=22.5 and i=21.6 using preliminary
photometric zeropoints from the NOT webpages. Compared to the R-band
magnitudes reported in GCNs 5797 and 5798, the afterglow has faded with
a temporal decay index of beta~0.6.
