Name: blood moon eclipse op 340 by Jeff Gburek
Duration: 6 min 45 s
Description: This meditation on this year's blood moon eclipse employs 5 layers of field recordings, two from this year and three others recorded on this day in the previous years. Enjoy the slow pace and open space. A work in progress., it is.

Between Earth and the Sun, space is not truly empty but is filled with a soup of charged particles called plasma. This plasma comes from the Sun, pumped out in a steady stream called the solar wind and sporadically blasted away in explosive solar eruptions. When this solar plasma strikes Earth, it causes the magnetic field lines and plasma around Earth to vibrate like the plucked strings of a harp, producing ultralow-frequency waves.

In 2007, NASA launched five satellites to fly through Earth’s magnetic “harp” – its magnetosphere – as part of the THEMIS mission (Time History of Events and Macroscale Interactions during Substorms). Since then, THEMIS has been gathering a bounty of information about plasma waves across Earth’s magnetosphere. 

The frequencies of the waves THEMIS measures are too low for our ears to hear, however. So a NASA citizen science project called HARP – or Heliophysics Audified: Resonances in Plasmas – has sped up the waves recorded by THEMIS to convert them to sound waves.

In this clip from February 19-22, 2012, whistle sounds are repeatedly heard over ambient background whooshes and crunches. The whistles change in pitch as a THEMIS spacecraft moves toward and away from Earth on three orbits, with a maximum altitude of about 50,000 miles. These sounds are related to Earth’s magnetic harp, which has longer magnetic strings and lower pitches farther away from Earth. These three orbits happened when the solar wind was blowing past Earth at a speed of about 1,200,000 miles per hour, which is fast even by solar wind standards! There’s often more harp activity during fast solar wind conditions. The solar wind also causes many other types of magnetic vibrations, most of which sound like background whooshes and crunches.

In this clip from March 2-5, 2012, whistle sounds are repeatedly heard over ambient background whooshes and crunches. The whistles change in pitch as a THEMIS spacecraft moves toward and away from Earth on three orbits, with a maximum altitude of about 50,000 miles. These sounds are related to Earth’s magnetic harp, which has longer magnetic strings and lower pitches farther away from Earth. These three orbits happened when the solar wind was relatively quiet, but it’s still able to pluck the strings of Earth’s magnetic harp while also causing many other types of magnetic vibrations, most of which sound like background whooshes and crunches.

Cafe Kafka

Frammento contenente due brani (Bambiente, Country Dub) registrato a Sacile PN, il 21 agosto 2005, per l'edizione di quell'anno di "Artistinsieme", bellissima e coloratissima mostra d'arte in strada che si è tenuta nell'ambito della antica Sagra degli Osei, durante la quale l'Orastrana ha suonato ininterrottamente per due giorni. Con Carlo Natali e Thomas Graber ai synth, elettronica, effetti e Mauro Rocchi al basso elettrico.

Nothing

Inspired by the following haiku written by Konishi Raizan, a famous haiku poet of the Genroku period (1688-1704).
spring dream…
not becoming unhinged
is what’s unbearable

Sound notes from an anomalous spring

Sound notes from an anomalous spring (Naviar haiku 596)

VLF & Radio Captures from June 5. Synthesizer and voice added June 11, for the Strawberry Moon and beyond. Partial text follows.
Lillacs few
due to drought
no doubt
this year...
How unscientific...
What an unscience
thing to say:
no doubt.
Plus the massive
excessive
pruning of the tree
plus the drought...
the lilacs 
few this year...
Should I 
stave off speech
until I get
statistical
support
for what I've seen?
lilacs few
this year
unlike the children
dead in Gaza

June 11 Lilacs Few This Year

is there no gentle place?
