GCN Circular 1818
Andrew Levan (U. Leicester/STScI), Mike Merrill (NOAO), Evert Rol (U. Amsterdam), Ian Dell'Antonio (Brown), James Rhoads and Andrew Fruchter (STScI) report for a larger collaboration: We observed the field of GRB 030115 (GCN 1816) with the KPNO 2.1m telescope, beginning at Jan 15th 08:27 UT (5.1 hours after bursts). Two epochs of imaging, approximately 4 hours apart, were obtained in each of J,H and K. A PSF matched image subtraction reveals a fading point source at a position of RA = 11:18:32.6, Dec= +15:02:59 The source is fixed on the sky and seen to fade in all bands, although unfortunately we do not currently have a reliable photometric calibration. An object is present at a position roughly consistent with the radio source detected in GCN 1817. However this source does not vary throughout our observations. K-band images of the field and possible transient are posted at http://www.stsci.edu/~fruchter/GRB/030115 Detailed analysis of the dataset is underway, and further observations are planned.
