We have obtained 9720-second exposure (18 dithered images, 540 s each)
the Rc (Bessell) at the position of GRB 981226.
Data have been carried out from 4th to 5th October 2000 at the
ESO-VLT UT1 telescope with FORS1 under seeing conditions of ~0.7 arcsec.
These observations are part of a survey of host galaxies (Saracco et al.
Prog. ID: 66.B-0539(A)).
We reach a limiting magnitude fainter than Rc=27.5 in the final co-added
(S/N=3 within the seeing disk).
We clearly detect a galaxy at the position of GRB 981226 as previously
found by Holland et al. (2000; GCN #749).
We measure a magnitude (Vega) Rc=24.8(+-0.1) (galactic extinction
within an aperture radius of 2 arcsec.
