The ANITA (ANtarctic Impulsive Transient Antenna) is a NASA long-duration balloon payload with an array of radio antennas. The primary goal of ANITA is to search for ultra-high energy cosmogenic neutrinos by detecting their impulsive radio signals emitted via the Askaryan effect in the Antarctic ice sheet. Moreover, ANITA is able to detect radio impulses produced from ultra-high energy cosmic-ray showers as result of their emissions via interaction with the geomagnetic field. The ANITA-IV experiment was launched on December 2, 2016, and successfully completed 28 days of flight. We will present the ANITA-IV instrument, flight operation, calibration as well as the status of the data analysis.
