Flewelling (IfA/Hawaii) report on\nbehalf of the ROTSE collaboration:\n\nROTSE-IIId, located at the Turkish National Observatory at\nBakirlitepe, Turkey, responded to GRB 120326A (Swift trigger 518626;\nSiegel et al., GCN 13105), producing images beginning 9.9 s after the\nGCN notice time. An automated response took the first image at\n01:20:51.9 UT, 22.6 s after the burst, under fair conditions. We took\n10 5-sec, 10 20-sec and 10 60-sec exposures. These unfiltered images\nare calibrated relative to USNO A2.0 (R). Imaging is on going.\n\nComparison to the DSS (second epoch) reveals no new sources within the\n3-sigma Swift/BAT error circle or the XRT error circle, for both\nsingle images and coadding into sets of 10. Individual images have\nlimiting magnitudes ranging from 14.7-16.7; we set the following\nspecific limits.\n\nstart UT       end UT      t_exp(s)   mlim   t_start-tGRB(s)  Coadd?\n--------------------------------------------------------------------\n01:20:51.9   01:20:56.9         5     14.7           22.6       N\n01:20:51.9   01:22:59.9       128     16.3           22.6       Y",
