Solar Research

The Owens Valley Solar Array (OVSA) is the only solar dedicated radio observatory in the US and therefore plays an important role in supplying the community with high spatial, temporal and spectral resolution microwave observations of the solar atmosphere.

Currently, the array consists of two 27-m antennas together with seven 2-m dishes which observe the Sun typically at 39 frequencies between 1.2 and 18 GHz. We are now embarking on a major expansion of the array by adding 8 more 2-m antennas, and greatly improving the system. See OVSA Expansion Project for more details. In addition to this main instrument, we also are developing two other instruments, the FASR Subsystem Testbed (FST). Our research currently focuses on:

  • Transient energetic phenomena
    • Energy release
    • Plasma heating and electron acceleration
    • Electron transport
    • Formation and destabilization of large scale structures
  • The nature and evolution of coronal magnetic fields
    • Measurement of coronal magnetic fields
    • Temporal evolution of coronal magnetic fields
    • The role of coronal currents
    • The storage and release of magnetic energy
  • The effects of solar-produced radio noise on wireless systems on or near Earth
    • Effects of solar bursts on cell phones
    • Effects of solar bursts on the Global Positioning System (GPS)
