Abstract
Analysis of the ANITA-1 data demonstrated the instrument was sensitive to UHECRs [1]. Unfortunately the optimisation of ANITA-2’s trigger to UHE neutrinos, which involved running on VPOL signals only, was severely detrimental to ANITA-2’s UHECR acceptance. However, the three remaining HPOL signals after all analysis cuts suggest that there may still be UHECR signals in the ANITA-2 data.

Modifications to the trigger system for ANITA-2 were completed before analysis in [1] demonstrated that ANITA-1 had observed UHECR-induced geosynchrotron radiation.
