GCN Circular 7165
A. Soderberg, E. Berger (Princeton), D. Fox, A. Cucchiara (Penn State), A. Rau, E. Ofek, M. Kasliwal, and S. B. Cenko (Caltech) report on behalf of a large collaboration: "We observed the optical counterpart to the X-ray transient in NGC 2770 (GCNs 7159, 7160) with the Gemini-N/GMOS and Palomar 200-inch/COSMIC spectrographs beginning at Jan 11.3 UT. The exposure times were 2x600 sec and 2x900 sec for the Gemini and Palomar data, respectively. A preliminary analysis of the reduced spectra reveals that the optical counterpart has a smooth, featureless continuum. We note that there is some suggestion of a broad bump near 5500 Ang which may indicate the emergence of SN features. Further analysis is in progress."
