[AK-VHF] Asteroid Bounce Experiment using HAARP - Dec.7, 2022 on 9.6 MHz

 From ARRL Newsletter - Dec.22, 2022:

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).

HAARP antenna array at the University of Alaska, Fairbanks.

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 Dec. 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 to the HAARP 
facility at uaf-gi-haarp at alaska.edu and request a QSL card by mailing a 
report to:
