N. Tanvir (U. Leicester) on behalf of a large collaboration report:
On 2009 April 19 at 12:53:50 UT we observed the Swift-BAT Slew Survey
GRB 090418B (Copete et al., GCN Circ. 9159) with the 2-m Faulkes
Telescope North using the i' and R filters.
From a set of 6x300 s frames in each filter, we could not find any
uncatalogued object inside the BAT error circle with respect to the SDSS
field stars, down to the following limiting magnitudes:
Mid Time Exposure Filter Limit
(days) (s) (mag)
-------------------------------------
1.17 6x300 i' > 21
1.20 6x300 R > 21.5
