In past years most Jove observations have focused on Io - related emissions. Recently, many periods of non-Io-A related activity have been observed in addition to the Io-related emissions. The non-Io-A activity is predominately L-bursts.

We encourage observers to also monitor during non-Io-related times as determined using their Radio Jupiter Pro software. Simply stated this means observing during times when the central meridian longitude of Jupiter is in the range of 225-280° as seen on the CML/Io Phase plane display in Radio Jupiter Pro.

Gainesville, Florida — Local Radio JOVE members will provide a radio astronomy exhibit at the annual Starry Night event at the University of Florida Museum of Natural History from 6pm to 10pm on November 30th, 2012. Starry Night is a program designed to bring awareness of astronomy and science to the public by offering free activities and displays. The radio astronomy exhibit will be set up outdoors, near the optical telescopes.

Attendees will be able to see a Jove receiver in action with a real-time strip chart, plus an SDR-14 functioning as a real-time spectrograph. Recorded examples of Jovian S-bursts and L-bursts will also be heard.

Dr. Ata Sarajedini, Professor and Associate Chair of the University of Florida Astronomy Dept. lead the UF group that participated in the USA Science and Engineering Expo in Washington D.C. on April 28-29. The UF theme for this year was "Gators in Space". He kindly carried about 60-70 RJ brochures that he completely distributed during the expo.

The Radio Jove project thanks Dr. Sarajedini and the University of Florida for their support

The Society of Amateur Radio Astronomers' booth at the 2012 Dayton ham radio "Hamvention", May 18-20 in Dayton, Ohio, U.S.A. provided visitors with information and items about Radio JOVE. Our thanks to Bill and Melinda Lord from SARA for their help in promoting our project.

On October 29th, Earth made its closest approach of the year to Jupiter. With the Sun, Earth, and Jupiter lined up, Jupiter was at opposition and transited at local midnight. As we pull ahead of the King of Planets, Jupiter will be high in the sky after sunset. Radio observations can now be made during those more civilized evening hours. Its a great time to listen. December got off to a fantastic start with a phenomenal Io-B storm on December 1.

Gainesville, Florida — Radio astronomy was represented by several Radio JOVE members at the annual Starry Night event at the University of Florida on November 3rd.

Radio JOVE participants (L to R) Dave Typinski, Francisco Reyes, and Wes Greenman.

Starry Night is a program designed to bring awareness of astronomy and science to the public by offering free activities and displays. The outdoor portion consisted of several telescopes viewing the Moon, Jupiter, and several close binary stars. Radio astronomy was represented by the Radio JOVE display.

The Radio JOVE exhibit consisted of a single dipole strung between two palm trees (it is Florida, after all!), a Jove receiver with a real-time strip chart, and an SDR-14 with a real-time spectrogram. Visitors were also treated to recorded examples of Jovian S-bursts and L-bursts.

Fantastic Io-B storms received recently. Some bursts were over a million degrees (about 15 dB above the galactic background). There has also been enhanced non-Io-A activity. Jupiter just passed opposition so it is transiting before midnight now. Its a great time to observe - so dust of your Jove antenna, fire up that radio, and submit your results to the Jove archive. We have been thru a long spell of rather weak Jupiter signals, but now conditions are much more favorable (the Jovicentric declination De of Earth is near its peak value). We expect Jupiter to turn in a great performance over the next few years.

While it has been known to happen, observing a solar radio burst in the middle of the night is a rare event. On August 4, 2011, a number of folks in the Western Hemisphere captured a strong solar burst near midnight, U.S. Eastern time (03:58Z). The same event was observed elsewhere, including just before sunrise in Western Europe.

Radio JOVE participants have been capturing lots of radio outbursts from the King of the Planets. Fire up your RJ decametric telescope and see what storms you catch. Submit your observations to the Radio JOVE Data Archive.

The Radio JOVE project teamed with the Society of Amateur Radio Astronomers to promote amateur radio astronomy at the ham radio "Hamvention" in Dayton, Ohio on May 20 - 22. There were Radio JOVE kits there for purchasing as well as other radio-related projects of interest.

See the Hamvention web site for more information about this event.

Here is the Radio Jove telescope at the Mars Desert Research Station (MDRS), a project of The Mars Society, an international non-profit humans to Mars organization. Located near Hanksville, UT.

Jupiter is rapidly moving toward the Sun's position in the sky and now appears near the western horizon in the evening twilight. This signals the end of another Jupiter observing season. Or does it? During times of minimum solar activity Jupiter can be observed during daylight hours because the earth's ionosphere is reasonably transparent to decametric radio waves.

Jupiter signals have been received as recently as mid-February by RJer Dave Typinski. Even though solar activity is on the rise it might be worth taking a daytime listen for Jupiter as it heads for conjunction with the Sun on April 6, 2011.

In February Radio JOVE shared an exhibit table at the 2011 HamCation with the Society of Amateur Radio Astronomy (SARA) at the Central Florida Fairgrounds in Orlando, Florida. Our folks chatted with numerous folks at the event, and answered many of their questions.

As the season winds down Jupiter intensity has been increasing as of late. Weak emission was detected around 0018 UT but increases towards the storm end to above 2 million degrees Kelvin.

The 20.1 MHz polarimeter shows primarily Right Circular Polarization (Red) throughout the storm as expected from the Io-B source. The spectrograph shows wideband L-burst emission cut-up by the horizontal Faraday Lanes. Modulation Lanes can also be seen as 45 degree emission from high to low frequencies cutting across the lower part of the spectrum.

The Radio Jove project was honored to accept a request by the Society of Amateur Radio Astonomers to present the keynote speech at this year's annual meeting at the National Radio Astronomy Observatory in Green Bank, WV, July 4-7, 2010. (http://www.radio-astronomy.org) The presentation generated some interesting discussion and it was also possible to inspect a state-of-the-art example of a Radio Jove setup brought by Bill and Melinda Lord.

Next year's SARA conference will be June 26-29, 2011 so make your plans now.

Jupiter Season is now in Full Swing!

We hope you can join us and observe Jupiter for this season -- the season runs until November 2009. We would like to note that we have even had success observing Jupiter well after sunrise; the reason is that the Sun is so quiet right now. We will have coordinated observing sessions in the future to help you with you observations. Stay tuned for these announcements.

Radio JOVE to Participate in the 100 Hours of Astronomy Event

One of the coming events for the International Year of Astronomy is the "100 Hours of Astronomy" scheduled for April 2-5, 2009. (See http://www.100hoursofastronomy.org/) . One of the key goals of 100 Hours of Astronomy is to have as many people as possible look through a telescope as Galileo did for the first time 400 years ago. Many star parties and other celebratory events around the world will happen during the 100 Hours.

Radio JOVE would like to participate by having as many radio telescopes as possible running continuously for the 100 hours, sending out their signals on the web for most or all of that time. Even if you can't run your equipment continuously, having it running as much as possible would be wonderful. Another possibility would be to take Radio JOVE equipment to a local star party, set it up, and show others that optical astronomy is not the only way to learn about the universe.

Radio JOVE Mourns Passing of Dr. Ron Parise

Dr. Ronald A. Parise, one of the original Radio JOVE Project team members and a long-time friend and colleague of many of those on the Project, lost his battle with cancer on May 9, 2008. Ron helped guide Radio JOVE in its early years and developed the first dedicated software for it. Many will remember Ron for his role as payload specialist on Space Shuttle missions STS-35 and STS-67 where he conducted important ultraviolet astronomical observations with the ASTRO-1 and ASTRO-2 payloads.

Our hearts are heavy with this sad news here at Radio JOVE.

Solar Cycle 24 has Begun

Solar cycle 24 has been recognized as having begun in early 2008. New solar cycles always begin with a high-latitude, reversed polarity sunspot. The region of magnetism that appeared back in December 2007 achieved high latitude (24 degrees North) and was magnetically reversed, but no supporting sunspot appeared until 25 days later.

We can expect the level of solar activity to increase over the next 4-5 years. (See Observing the Sun.)
