   ARLX012 Amateur Radio Operators Invited to participate in Asteroid   
   Bounce Experiment   
      
   The High-frequency Active Auroral Research Program (HAARP) will be   
   conducting a research campaign/experiment on December 27, 2022, with   
   transmissions between 1100 - 2300 UTC (0200 - 1400 AKST).   
      
   This experiment will reflect HAARP transmissions off of Near-Earth   
   Asteroid (NEA) 2010 XC15, and the echo will be received by the Owens   
   Valley Radio Observatory Long Wavelength Array (OVRO-LWA) at the   
   California Institute of Technology (Caltech) and by the University   
   of New Mexico's Long Wavelength Array (UNM-LWA). The target asteroid   
   will be roughly two lunar distances away from Earth at the time of   
   transmission. Characterizing the interior structure and composition   
   of NEAs is critical for advancing the understanding of solar system   
   evolution and aiding in planetary defense.   
      
   Actual transmit times are highly variable based on real-time   
   ionospheric conditions and all information is subject to change.   
   Currently, the Asteroid Bounce (2010 XC15) experiment will take   
   place December 27, 2022, from 1100 UTC to 2300 UTC; 9.6 MHz, LFM   
   (linear FM), 0.5 Hz WRF (waveform repetition frequency), 30 kHz   
   bandwidth. Reports recording echo are encouraged; demodulated   
   recordings in .WAV or .MP3 are recommended.   
      
   For real-time ionospheric conditions in Gakona, please consult   
   ionograms from the HAARP Diagnostic Suite at,   
   https://haarp.gi.alaska.edu/diagnostic-suite .   
      
   Amateur radio and radio astronomy enthusiasts are invited to listen   
   to the transmissions/echoes and submit reception reports via email   
   to the HAARP facility at, uaf-gi-haarp@alaska.edu, and request a QSL   
   card by mailing a report to:
