(all at TLS Tautenburg) report:
We re-observed the afterglow of GRB 110801A (M. De Pasquale et al., GCN
12228)
with the 2m/1.34m Schmidt telescope of the Thueringer Landessternwarte
Tautenburg starting about 24 hours after the GRB trigger.
A stacking of the first 15 minutes of the second epoch data does not show
the afterglow in the R band down to 21 mag (Vega system). We conclude that
a jet break has occurred within the last 24 hours.
