and N. Tanvir (U. Leicester) report on behalf of a larger collaboration:
On 2008 July 28 (01:35:55 UT) we began observing the field of GRB 080727C
(Parsons et al. GCN Circ. 8035) with the Liverpool Telescope.
Observations consisted of 6x300s exposures acquired using the SDSS-i'
filter.
In our coadded frame we do not detect any source inside the refined XRT
error box (Osborne et al. GCN Circ. 8038) down to the limiting magnitude
reported below.
Telescope Filter T_mid[s] Exposure[s] M_lim (3-sigma)
-------------------------------------------------------------
Liverpool SDSS-i' 9830 6x300 22.8
-------------------------------------------------------------
The calibration was performed using the I magnitudes of several USNOB-1
catalogue field objects. The value derived by us is consistent with
that given by Bikmaev et al. (GCN Circ. 8036).
