OBSERVATION REPORT A. Oksanen and M. Aho on behalf of Nyrola observatory GRB Team report: We have observed most of the the revised IPN error box (GCN 1650) of the GRB021020 with the 16-inch Meade LX200 telescope of Nyrola observatory in Finland. We took 9x240s Rc-band images centered on the GRB coordinates with SBIG ST7E CCD October 21, 2002 21:00-21:59 UT. The second epoch was imaged on October 22, 2002 19:29-20:57 UT (20x240s). From the combined frames no new or fading targets were found by comparison to DSS2 (R) and the second epoch (Oct 22.8 UT) images. Limiting magnitude on the first epoch about Rc=19.2 and second epoch Rc=19.5. The field is very crowded. Further image calibration and checking the extreme corners of the errorbox is in progress.
