A GCN Alert was issued at 03:22:41 UT, 7 sec after the beginning of the burst. Ground analysis of the WXM data produced a localization which was reported in a GCN Notice at 04:33:07 UT, 71 minutes after the burst. The WXM localization SNR was 22. The WXM location can be expressed as a 90% confidence circle that is 10 arcminutes in radius and is centered at WXM: RA = +11h 18m 41s, Dec = +15d 06' 54" (J2000). Ground analysis of the SXC data for the burst produced a further refinement in the location, which was reported in a GCN Notice at 04:46:34 UT, 84 minutes after the burst. The SXC localization SNR was 17. The SXC location can be expressed as a 90% confidence circle that is 2 arcminutes in radius and is centered at SXC: RA = +11h 18m 30s, Dec = +15d 02' 17" (J2000). The SXC localization may be improved. The burst duration in the 4-40 keV band was ~20 s. A total of 5030 counts were detected during that interval, corresponding to a fluence of ~9 x 10-7 ergs cm-2.

The B and V data only goes roughly as deep as DSS-2 due to cirrus and moonlight; the J and H datasets go significantly deeper than either DSS-2 or 2MASS. At the position of the afterglow candidate suggested by Levan et al. (GCN 1818) we confirm a fading object, visible on the 030115 UT H-band image but not on the 030116 UT H-band image. We measure the position of the counterpart on the 030115 UT image as: 11:18:32.61 +15:02:59.9 J2000 using the USNO-A2.0 reference catalog; estimated coordinate errors are +/- 200mas.

We measure for this object a magnitude R ~ 21.5, assuming R = 16.7 for the closeby USNO star U1050_06471524. A count excess at the position of this object appears to be present on the DSS2-Red also, suggesting that any R-band variability at the time of GRB030115 must be of low amplitude. The positional coincidence with the IR transient however strengthens the reality of this object even if it is close to the detection limit in both DSS2 and our R-band images. This object might be the host galaxy if the IR source is indeed the GRB afterglow. If this is true, the non-detection of a bright afterglow in the optical might be more likely due to a very high local extinction, rather than to the high redshift. The optical counterpart to the radio source detected by Berger et al. (GCN #1817) is well detected on both the DSS2 and our R-band frame as an extended object with magnitude R ~ 20.

Garnavich (University of Notre Dame) The field of GRB 030115 (HETE 2533) was imaged with the 3.5m WIYN telescope on 2003 Jan. 29.4 (UT). Five R-band images of 600s each were combined with an average seeing of 0.9". At the position of the IR transient reported by Levan et al. (GCN 1818) and Vrba et al. (GCN 1822) there is a faint source which is probably the host galaxy. If the USNO catalog star 14" west has R=18.8, then the brightness of the host is R=24.5 mag. Another galaxy 1.3" east appears nearly blended with the host. An image is available at http://www.nd.edu/~pgarnavi/grb030115.jpg .
