Lemmon, Arizona. The observation\nstarted at 05-04-03:24:30 UT. We detect the afterglow with a\nmagnitude at R ~ 20.28 +- 0.09 mag (mid-time of ~10.0 hrs after\nBAT alert) based on the photometry calibration star reported by\nUpdike et al.(GCN 12001).\n\nFurther analysis of the data and the follow-up observations of\nthe object is ongoing. We thank the LOAO operator, I.-K. Baek\nfor her assistance with the observation.",
