GCN Circular 8688
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.
