RADIO JOVE PROJECT "THE SUN IS BACK" "That Would Fry Some Onions" LATEST SOLAR OUTBURST
ANVIL SCREAMER: In a remote area of New Mexico, amateur astronomer Thomas Ashcraft operates a shortwave radio observatory. He routinely records bursts of radio energy from the sun and Jupiter, as well as echoes from passing meteors. On April 20th, a more hair-raising sound emerged from the loudspeaker. "It was the banshee howl of an 'anvil screamer.'" Click on the image for a sample of what he heard:
An "anvil screamer" is a burst of static caused by a thunderstorm passing directly over a radio telescope, raising strong electric fields around the antenna. "Small corona discharges occurred off of pointy objects (grasses and cactus spines) in the vicinity of the antennas due to a charge differential between the ground and the air," says Ashcraft. "I did not look outside because I was busy disconnecting sensitive electronics, but it is possible my antennas might have been glowing violet blue in this moment with St. Elmo's Fire."
"I was able to capture a one minute forty second radio recording, which builds in intensity and frequency and then stops abruptly as I got my system unplugged," he says. "I thought a lightning bolt would surely strike as the charged anvil of the thunderhead passed by, but a strike did not occur." Listen again. "It was a close call in any case." More information about the event may be found here.

There was a 60 dB above background burst near 1444 UT.
The type III storm activity (8 to 16 UT at Nancay) at times displayed several bursts per minute.

Heads up for possible strong flares today.
I am with Jupiter predictions these days but I just checked Radio Jupiter Pro and see there was a prime Io-B pass during the 0200 UT hour Feb 13, 2011.
I can hear some L bursting in my audio records from 0229 through 0233 UT.
Heads up , and Japan because it might have been a good storm where better positioned in the beam.

EXTRA! SOLAR RADIO BURSTS:
The August 7th flare produced intense radio bursts detectable by ordinary shortwave receivers on Earth. In New Mexico, amateur radio astronomer Thomas Ashcraft picked up strong emissions around 21 MHz. "Listen to some of the sounds than came out of the loudspeakers," he says. "This was a complex flare and very exciting. Yet it is still small stuff compared to what is coming in the future as Solar Cycle 24 intensifies."

The Radio JOVE project is a hands-on inquiry-based educational project that allows students, teachers and the general public to learn about radio astronomy by building their own radio telescope from an inexpensive kit and/or using remote radio telescopes through the internet. Participants also collaborate with each other through interactions and sharing of data on the network.
The Radio JOVE project began in 1998. Since then, more than 1100 teams of students and interested individuals have purchased our non-profit radio telescope kits and are learning radio astronomy by building and operating a radio telescope. This self-supporting program continues to thrive and inspire new groups of students as well as individuals
Radio JOVE students and amateur scientists observe and analyze natural radio emissions of Jupiter, the Sun, and our galaxy.

Radio JOVE at a Glance:
Teaches planetary and solar radio astronomy, space physics, electronics, and the scientific method
Target Audience - Teachers and students of high schools, middle schools, college science courses, and interested individuals
Provides participants with a hands-on radio astronomy experience for the classroom or for special projects
Gain experience in electronics construction and testing
Interact with other Radio Jove participants to exchange data, ideas, and experiences
Radio Jove Kits are available @ http://radiojove.gsfc.nasa.gov/office/order_form.htm
Solar Dynamics Observatory Daily Movies
The Atmospheric Imaging Assembly cameras are creating wonderful high resolution images of the Sun at several wavelengths. They are also available as daily movies.
I think they will be FUN to show High School students, at the same time they observe the Sun with Radio JOVE Kits, and Radio JOVE Participant data streams from around the world, and discuss Solar events of various types.

Space Surveillance Radar:METEOR ECHOES : The Air Force Space Surveillance Radar is scanning the skies above Texas. When a meteor or satellite passes over the facility--ping!--there is an echo. "Listen" http://www.spaceweatherradio.com/index.php
Listen To Saturn:
Recent data from NASA's Cassini spacecraft show that the variation in radio waves controlled by the planet's rotation is different in the northern and southern hemispheres. Moreover, the northern and southern rotational variations also appear to change with the Saturnian seasons, and the hemispheres have actually swapped rates. These two radio waves, converted to the human audio range, can be heard in a new video available online at: http://www.nasa.gov/multimedia/videogallery/index.html?media_id=74390781 (Or click the video below)

SUNSPOT MOVIE: Sunspot 1057 is crackling with C-class solar flares. Yesterday, amateur astronomer Michael Buxton of Ocean Beach, California, saw one with his own eyes. www.spaceweather.com
I attach 4 details from the STEREO WAVES spectrum:
near 1,5,10, and 18 UT.

The burst saturated my 21.1 MHz yagi. "Pegged the needle" on the as the old saying went. The 23.9 MHz top portion of the chart is a single half-wave dipole reception.
