Daniele Malesani, Johan P. U. Fynbo (DARK/NBI), Eric Stempels (Univ. St.
Andrews), and Tapio Pursimo (NOT), report on behalf of a larger
collaboration:
We observed the field of GRB 081221 (Hoversten et al., GCN 8687) with
the NOT equipped with ALFOSC. R-band imaging was carried out (12 min
exposure) with mean time Dec 21.81 UT (3.14 hr after the GRB). Inside
the XRT error circle (Hoversten et al., GCN 8687), we detect no source
down to a limiting magnitude R ~ 23. Further imaging is ongoing.
We note the presence of two faint sources just outside the XRT error
circle, at approximate coordinates (J2000):
1: RA = 01:03:10.26, Dec = -24:32:47.4, R ~ 22.3
2: RA = 01:03:10.10, Dec = -24:32:58.6, R ~ 23.0
We acknowledge excellent support from the NOT staff.
