GCN Circular 4471
J. S. Bloom (UC Berkeley) reports: "We have conducted further analysis on the source noted in GCNs 4465/4467 and suggest that, while the source is formally outside of the 90% containment BAT error circle (e.g. Torii GCN 4468), there is evidence this is the (bright) afterglow of GRB 060110 (Zane al. GCN 4463). This follows from a few lines of evidence:  evidence for fading. We created two mosaic epochs (1: 08:06:52 -- 08:11:32; 2: 08:12:46 -- 08:30:36) and found that the average brightness decreased by ~0.12 mag in JHKs. We believe that this fading is significant but photometry is complicated by large background gradients owing to the proximity to the Moon.  no bright minor planets are nearby this position (see GCN 4467).  no evidence for apparent motion between the epochs (~<1"/hr) and point-like PSF. All the other minor planets in the field have significant motions, particularly in RA (>10"/hr) Our current astrometric solution gives a position of the afterglow (in both epochs) to be: 04:50:57.85 +28:25:55.7 (J2000; 200 mas uncertainty). This is close to the position noted by Torii (GCN 4468) and lends credence to their tentative R-band detection. Photometry in the second epoch yields magnitudes J = 15.23, H = 14.25, Ks = 13.57 (absolute zp uncertainty of ~0.04 mag)." Follow on observations are urged.
