Hello All,

Just passing this along in case anyone wants to monitor this event. I'm
not sure but it looks like it might be an art project of some sort.





*Date: August 3, 2022To: Amateur Radio & Radio Astronomy CommunitiesFrom:
HAARP Program OfficeSubject: Notice of Transmission*

The High-frequency Active Auroral Research Program (HAARP) will be
conducting a research campaign from Aug. 8
to Aug. 14, with operating times specified in the table below. Operating
frequencies will vary, but all HAARP
transmissions will be between 2.8 MHz and 10 MHz. Actual transmit days and
times are highly variable based on
real-time ionospheric and/or geomagnetic conditions. All information is
subject to change.

This campaign is being conducted in support of the 2023 Polar Aeronomy &
Radio Science Summer School. Some
examples of the experiments are generation of artificial field aligned
irregularities, scintillation at VHF and UHF in
an artificially altered ionosphere, mapping of the auroral electrojet
structure, modulation of the conductivity of the
D-region ionosphere, and production of SLF, ULF and VLF emissions by
pulsing the HAARP HF transmission on and
off. Experiments benefiting from amateur radio support or having citizen
science applications are noted below.

Ghosts In The Airglow (GITAG) – The final part of a three-part transmission
art project funded by the Canada
Council for the Arts, mixing audio and images at the boundary between
Earth’s atmosphere and outer space. For
Composition No. 3, Christie has invited contributions from other artists
including, Vladyslav Atavin, José Alejandro
Rivera, Sarah Nance, Rasu-Yong Tugen, Geneviève D’Ortun, and T. D. Walker.
This composition also includes Morse
code transmissions created by turning the HAARP pulse on and off. Another
new experiment being tried in this
composition is the creation of a drawing in the waterfall.

As a citizen science experiment to learn more about propagation, shortwave
listeners from around the world are
invited to tune in and submit reception reports in exchange for QSL cards.
Transmission frequencies will be listed
on the project's new website www.ghostsintheairglow.space, and reception
reports can be submitted using the
online form which is also on the website. For those who do not have access
to shortwave radio equipment, the
project will also be streamed live on the home page of the project’s
website. There are frequently two frequencies
transmitted simultaneously, and as such there are two videos embedded side
by side (one for each frequency) that
can be viewed simultaneously.

A supplement accompanies this Notice of Transmission that provides general
information for HAARP Radio
Enthusiasts as well as some information on the application of software
defined radio receivers in detecting,
demodulating and monitoring HAARP transmissions.

*General Information for HAARP Radio Enthusiasts:*

1) The HAARP Ionospheric Research Instrument (IRI) transmits only in the
frequency range 2.695 to 9.995 MHz, with
certain frequencies blocked out as specified in the FCC license for call
sign WI2XFX. The emission bandwidth may
be up to 46 kHz wide depending on the frequency and experiment.

2) The types of modulation vary with the experiment requirements. Some
emission designators are 16K0M0N,
26K0P0N, 40K5A3N, 43K0H0N, 46K0F3N, and 46K0N0N. Emission designators are
not specified in HAARP
experiments.

3) Most experiments depend on ionospheric and geomagnetic conditions that
are mostly unpredictable. The
transmission frequencies for a given experiment may change to track changes
in those conditions with little or no
notice.

4) A scheduled experiment that depends on certain ionospheric or
geomagnetic conditions may be rescheduled or
cancelled if the required conditions do not occur.

5) The IRI may be setup to simultaneously transmit two modulated or
unmodulated carriers depending on the
experiment requirements.

6) To request a HAARP QSL card, send reception reports to: HAARP, P.O. Box
271, Gakona, Alaska 99586 USA.
Please note that due to the volume of requests received, it may take some
time to respond to your request.

*Monitoring HAARP IRI transmissions with a Software Defined Radio Receiver:*

1) Listeners with an SDR receiver capable of 8 MHz bandwidth can monitor
the entire frequency band noted above;

2) Most IRI transmissions Start and End on the minute; that is, when
HH:MM:SS = HH:MM:00, where HH is the UTC
hour, MM is the minute and SS is the second;

3) When a carrier is seen to pop up on the SDR’s displayed spectra, the
listener can identify the center frequency
using the SDR software and then reduce the bandwidth to further monitor,
demodulate or analyze the signal;

4) If two SDRs are available, one can be used in a wideband mode to locate
the signals and the other can be used in
a narrowband mode to analyze, demodulate or monitor the signals;

5) Since the maximum emission bandwidth is 46 kHz (±23 kHz), SDRs with a 50
kHz bandwidth setting are able to
monitor the entire modulated signal after it is located. The center
frequency may be stepped through a range of
frequencies or may change according to experiment requirements to another,
far removed frequency;

6) Not all experiments use the full 46 kHz bandwidth, some use only a pure
carrier and some use single sideband;

7) Radio propagation conditions and the IRI beam direction will affect the
reception of the IRI transmissions or cause
a fadeout at the receiver location. Propagation conditions and beam
directions can change significantly and
rapidly during an experiment;

8) Some experiments require the IRI beam to be pointed along the local
magnetic zenith. This means the beam is
pointed parallel to the local magnetic field lines, or approximately 75°
elevation and 16° east of north;

9) Although the HAARP IRI transmits only in the HF range (see above), the
transmissions can and some experiments
are designed to generate SLF, ULF, and VLF emissions in the D/E-region
ionosphere. Modulated heating of the
D/E-region electrons by the HF transmissions in turn modulates the plasma
conductivity, which generates a
virtual antenna at altitudes between 70 and 85 km. Emissions up to 20 kHz
have been demonstrated but most are
below a few kilohertz. These low frequency emissions can propagate in the
Earth-Ionosphere Waveguide or by
other mechanisms, depending on frequency, and conceivably can travel great
distances.
