In-Flight Performance of the Payload for Ultrahigh Energy Observations (PUEO)

The Payload for Ultrahigh Energy Observations (PUEO) is a balloon-borne experiment designed to detect radio signals from interactions of the highest energy neutrinos (>1EeV) in ice. Building off the success of its predecessor, ANITA, the PUEO instrument combines technological improvements with more receiving antennas to achieve an order of magnitude increase in sensitivity. These improvements will allow PUEO to set world-leading constraints on the ultrahigh energy (UHE) neutrino flux or make the first detection of neutrinos at these energies. PUEO is scheduled to fly during the austral summer of 2025/2026 over Antarctica, monitoring the ice sheet for UHE interactions. This talk will present a summary of the campaign, including launch, operations, field calibration, and termination, along with a first look at the data quality from the flight.
