OBSERVATION REPORT A. Oksanen on behalf of Nyrola observatory GRB Team report: A 24 x 16 arcmin field covering the HETE SXC error box of GRB 031220 (HETE 2976) was imaged with the 0.4m SCT at the Nyrola Observatory starting at December 20, 2003 17:17 UT, 13.9 hours after the burst under good conditions, but with high airmass. Total of 21 240s Rc-exposures were sigma reject combined and compared visually against the Digitized Sky Survey (DSS2R) and by using software to find stars not existing on USNOA2.0 catalog.
