TITLE: GCN CIRCULAR NUMBER: 2705 SUBJECT: GRB040912 : Kiso Optical follow-up observation DATE: 04/09/13 07:52:51 GMT FROM: Yuji Urata at RIKEN K. Ogura(Kokugakuin Univ.), S. Nishiura (Tokyo Gakugei Univ.) M. Isogai(Tokyo Univ.) and Y. Urata(RIKEN) report: " We have imaged the entire HETE-2 error circle (Butler et al., GCN 2701) using Kiso 1.05 m Schmidt telescope with 2kx2k CCD camera starting at 2004 Sep 12.668 UTC. We obtained 3 x 300 sec R-band images. Each R-band image gives limiting magnitude of R~20 mag. using R magnitudes of near USNO_A2.0 stars as photometric references. We found a source around "23:57:10 -00:56:42" (R~19.4 mag.) which is not in DSS II images. But, comparing our second image with our third one, it seem to move about 4 arcsec in 5 minute. It may be minor planet. Because of our network trouble we cannot access "MINOR PLANET CHECKER" page now." This message may be cited.
