[18.06] Monitoring Solar Radio Bursts at 20.1 MHz with the Furman University Radio Jove Telescope

J.R. Holtzclaw, D. A. Moffett (Furman University)

For an interval of two months, from June 1, 2003 to July 28, 2003, we monitored solar radio bursts at 20.1 MHz using a Radio Jove dual-dipole transit antenna and receiver. We correlated these bursts with those recorded by similar receivers across the US and Europe (available at NASA’s Radio Jove Archive center), and with radio and X-ray events logged by NOAA’s Space Environment Center.

Most of the recorded events were Type III radio flares, easily observed at 20.1 MHz. Solar Type III events stem from Langmuir plasma waves created by electrons accelerated during the magnetic reconnection events of solar flares. The plasma wave frequency depends on the electron density, so the radio bursts sweep either from centimeter to decameter wavelengths or the reverse as the plasma waves traverse the sun’s corona. If accelerated toward the Sun, the charged particles can create X-ray flares. We show examples of both correlated and anti-correlated radio and X-ray flares.

We acknowledge the use of NASA’s Radio Jove Archive and those individuals who submitted its data, as well as data provided by the Space Environment Center's solar data archives. Radio Jove is a NASA Education and Outreach Project. SEC is administered by the National Oceanic and Atmospheric Administration.
