TITLE: GCN CIRCULAR NUMBER: 11872 SUBJECT: GRB 110328A/Swift J164449.3+573451: SARA-N detection DATE: 11/04/03 03:37:13 GMT FROM: Adria C. Updike at Clemson U William C. Keel, Erin Darnell (U Alabama), Adria C. Updike (NASA/GSFC), D. Alexander Kann (TLS Tautenburg), and Dieter H. Hartmann (Clemson University) report: We observed the field of GRB 110328A/Swift J164449.3+573451 (Cummings et al., GCN 11823) on April 1 at 11:50 UT (3.96 days after the trigger) for 20 minutes in the R band with the SARA North telescope at KPNO. At the location of the optical counterpart (Cenko et al., GCN 11827; Volnova et al., GCN 11837) we marginally detect the transient at R = 21.7 +/- 0.3 as compared to the USNO B1.0 catalog and the comparison star given by Leloudas et al. (GCN 11844), in good agreement with the earlier observations of Kelemen et al. (GCN 11867). This GCN resulted from a collaboration initiated by the BAUTforum. This message may be cited.
