Abstract 
GRB041006 is a gamma-ray burst which was originally detected by HETE-2 at 12:18:06 Oct. 6 in 2004. Our 
30cm telescope(RIMOTS) has succeeded in observing the optical afterglow of it with unfilterd cooling CCD 
camera only 70 seconds after the burst. First three images were slightly flowed. Standard method of photometry 
cannot be applied to these images. We have developed an original method to analyses these images. This method 
was confirmed to work properly to get the correct magnitude of afterglow. By using this method, it was able to 
obtain the very early light curve of optical afterglow that there are few observation until now
