larger GRB follow up collaboration report:
We observed the field of GRB 060204C (Grupe et al., GCN 4663) in R-band
with the 60 cm telescope of peak Terskol observatory starting Feb. 04 (UT)
20:56. Totally we obtained 27x60 s images in two epochs (UT) 20:56-21:10,
and 21:22-21:35. Within whole BAT error circle in a combined image we found
an object which is marginally visible in DSS2(R) and not presented in
USNO-B1.0; coordinates of the object are (J2000) RA= 06h 10m 38.4s Dec=
+70 09 32.4 with uncertainty in both coordinates of about 0.1". Brightness
of the object is measured in the combined image is R=19.2 +/-0.1. The object
is not variable between the two epochs within error bars. The astrometry
and photometry calibration is based on USNO-B1.0.
While the object is not variable between our epochs and marginally visible
in DSS2(R) and detected better in DSS2(I), the object may be a host galaxy
of GRB060204C if fading brightness of the object will be confirmed.
