Abstract
The SunRISE Long Wavelength Antenna (LWA) Array Deployment team at the University of Michigan, in collaboration with NASA’s Jet Propulsion Laboratory (JPL), investigates solar radio bursts (SRBs) using a Dual Dipole Antenna (DDA) and a Long Wavelength Array (LWA) Active Crossed-Dipole Antenna. These instruments collect low-frequency solar radio emissions across 16–24 MHz (DDA) and 5–85 MHz (LWA) to study solar flares and coronal mass ejections (CMEs). This study examines the correlation between Type III SRBs and GOES X-ray flux intensity. We recorded 61 Type III SRBs associated with solar flares ranging from C1.0 to X8.7 W/m². Each burst occurred during the rise (33), peak (6), or decay (24) phase of its associated flare. A logarithmic linear regression of SRB intensity (dB) versus GOES X-ray flux (W/m²) yielded: y = 901.16 · log10(x) + 10,665.34, where x is GOES X-ray flux (W/m²) and y is SRB intensity (dB), indicating that stronger flares produce more intense Type III SRBs. To assess spatial correlations, we mapped Type III SRB locations by their associated flare positions on a solar disk graph, categorized by rise, peak, or decay phase. However, no significant correlation was found between burst timing and flare position. These findings confirm a strong correlation between Type III SRBs and solar flares. Further investigation of Type III bursts could refine their role in solar flare prediction models, improving space weather forecasting and mitigation strategies for satellites, astronauts, and space-based technologies.
