Description
The Telescope Array Experiment has observed a cluster of the UHECRs, called the Hotspot,
with $E>57$ EeV around Ursa Major (Abbasi et al., ApJ, 790, L21) using the first five years of data by the TA surface detectors. In this work, we will report on an update of this result using the latest data collected by the TA surface detectors.
