Myungshin Im, Won-Kee Park (CEOU/Seoul National Univ), 
Soojong Pak, Giseon Baek, and Youngseok Oh (Kyunghee University)

We revise the position of the afterglow candidate to be

   RA=22:52:46.49
   Dec=70:17:53.6
   with a positional error of ~0.5".

The 2nd set of i-band images were taken 3 hrs after
the 1st set (Im et al. GCN 12295Not found
 
 
). Our analysis of the data
shows no significant fading of the object (dm < 0.1  mag)
during that time span.
