Description
Since 2007 the Telescope Array Project (TA) and Pierre Auger Observatory (Auger) have collected extensive data sets spanning several orders of magnitude of the cosmic ray spectrum. In both experiments the bulk of data is generated from the surface detector (SD) array which are energetically calibrated with fluorescence detectors using a hybrid approach. However, each experiment has implemented a different SD station design, resulting in different sensitivities of extensive air shower channels. Understanding these differences and any potential unforeseen systematic errors are essential for future joint analyses. In this paper we present an update on the progress of this in situ cross calibration program. We focus on recent hardware installations which enable the readout of co-located Auger and TA SD stations at the TA Central Laser Facility. We present a preliminary analysis of TA reconstructed showers also detected by Auger SDs. Finally, we briefly share some details of plans for the second phase of the program: installation of a functional micro array of prototype Auger North SD stations.
