P. Ferrero (IASF-CNR, Bologna; Osservatorio e Universita' di Teramo),
G. Pizzichini (IASF-CNR, Sezione di Bologna), F. Giovannelli(IASF-CNR,
Sezione di Roma) and R. Gualandi (Osservatorio di Bologna) report:

We observed the error box of GRB040825A (HETE Ground Analysis, trigger
11553) with the 152 cm Loiano Telescope and the BFOSC camera system in
non optimal sky conditions (seeing approximately 3.5 arcsec).
We obtained 10X300s images with a filter Rc at UT mean = 26.03516.
The magnitude limit, estimated by comparison with USNO A2 catalog, is
approximately 19.5.
By comparison of the coadded images with the corresponding DSS plate
we did not find any obvious OT source, but in our field we detected
2 moving objects.
The coadded images and the observation log will be posted in our
public directory from where it will be possible to retrieve by sftp
using hostname: ermione.bo.astro.it, username: publicGRB, password:
GRB_bo, directory: GRB040825A.
