Goode Solar Telescope

The Goode Solar Telescope is a major observing instrument with a 1.6-meter opening located at the Big Bear Solar Observatory at an elevation of 2060 meters. It uses a special Gregorian design that collects light from the side to produce images without obstruction.

The telescope began scientific observations in 2009 and received its current name in 2017 to honor Philip R. Goode, director of the Solar Research Center at NJIT. The naming recognized his significant contributions to solar research.

The facility draws researchers from around the world who come together to study the sun and share their discoveries. This international collaboration has made the site an important hub for solar research.

The telescope benefits from its location near Big Bear Lake, where atmospheric conditions remain stable and allow for excellent observations. An adaptive optics system automatically compensates for air turbulence to deliver sharp and detailed images of the sun.

The instrument can detect solar features smaller than 50 kilometers, which represents extraordinarily high resolution. This capability comes from its special off-axis Gregorian design that avoids light loss and allows extremely detailed observations.
