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. No new objects were found to the image limit of R=20.5.
