GRB 190627A: Discovery Channel Telescope late time observations
Abstract
We observed at the optical counterpart of GRB 190106A (Sonbas et al., GCN 24888) using the Large Monolithic Imager (LMI) on the 4.3m Discovery Channel Telescope (DCT) at Happy Jack, AZ. Observations started on July 05, 07:46:14 UT (about 7.85 days after the Swift trigger) with SDSS r and i filters. We detected the optical counterpart (Siegel & Sonbas, GCN 24889) measuring the following AB magnitudes: Start Time Exposure Filter Magnitude (days from trigger) (s) ------------------------------------------------------- 7.85 4x300 r' 23.36 +- 0.11 7.87 4x300 i' 23.17 +- 0.11 ------------------------------------------------------- Magnitudes are calibrated against Pan-STARRS catalog. We thank the staff of the Discovery Channel Telescope in particular Casey Kyte, Ishara Nisley for assistance with these observations.
