GRB020819 image
FIT (average combined)


We observed the GRB020409 (HETE 2275) error circle (GCN 1508)
at Nyrola observatory. Our 80 minutes (20 x 240s) R exposure started 
August 19, 2002 20:31 UT, about 5 hours after the HETE trigger.

Telescope: 16-inch Meade LX200 working at f5 + SBIG ST8E CCD.

The image shows no new objects inside the WXM or SXC error circles 
brighter than the limiting magnitude of R=19. 

The bright star on the image is 4.5 magnitude Theta Piscium. 
There are also several internal reflections in the 
image as well caused by the very bright star.
