TITLE: GCN CIRCULAR NUMBER: 6034 SUBJECT: GRB 070125: Continued P60 Observations DATE: 07/01/26 11:02:12 GMT FROM: S. Bradley Cenko at Caltech S. B. Cenko (Caltech) reports on behalf of a larger collaboration: We have continued to monitor the proposed optical afterglow of GRB 070125 (GCN 6028) with the Palomar 60-inch telescope. We began a new series of R-band observations at ~ 9:29 UT 26 Jan. Using 50 point sources from the 2MASS catalog, we have refined the astrometry of our imaging. The updated position (J2000.0) for the optical candidate is: RA: 07:51:17.767, Dec: +31:09:04.11 with an uncertainty of +/- 0.3" in each coordinate. The position of the source is consistent between the two epochs, placing an upper limit on any proper motion of <~ 0.06 arcsec / hr. Furthermore, from a preliminary analysis of the photometry, we find evidence the source has faded by ~ 0.13 mag between our two epochs. Observations and analysis are continuing. Given the unusual nature of the spectrum of this object (Prochaska et al., GCNs 6031 & 6032), we urge further optical monitoring to confirm this object is indeed the optical afterglow of GRB 070125.
