We have imaged the BeppoSAX revised error-box of GRB000615 (GCN 705)
using the AZT-24 1.1-meter telescope at Campo Imperatore (AQ). We
observed for a total exposure time of 3600 sec in J-band and 1500 sec
in K-band. Observations started at June 15.9792 UT about 17.2 hours
after BeppoSAX trigger time (GCN 703) and ended at 16.09167 UT. We
imaged the field in J-band twice with a time interval of about 2 hours.
The limiting magnitude in the combined images is J=20.5 mag and K=17.5 mag
(S/N=3) with an average seeing of 2.5" . A preliminary comparison of the
first 900 sec with the last 1500 sec J-band images reveals no obvious fading
objects. The comparison of the combined 3600 sec J-band images with the
POSS-II red plate and the FLWO field (GCN 706), reveals no obvious new
objects.
Further observations of this field are planned at Campo Imperatore.
