2007 Jovian activity published in the Radio Jove Archive

The Radio Jove Archive shows entries for 24 days in 2007, from January to August. The Calendar above shows the 6 active days in April, one of the two most active months in the year.

John H. Thomas, W3FAF Radio Observatory, recorded an Io-C event on April 12. His Log notes he was using a 6 element tracking Yagi, with an Icom IC R75 receiver tuned to 20.92 MHz.
