Big Bear Solar Observatory, Solar observatory in Big Bear Lake, California, United States.
The Big Bear Solar Observatory features a 1.6-meter diameter telescope positioned at 2,060 meters elevation on the northern shore of Big Bear Lake, utilizing specialized instruments designed for high-resolution solar observations and magnetic field analysis.
Founded in 1969 by the California Institute of Technology and later transferred to the New Jersey Institute of Technology in 1997, the observatory became operational with its New Solar Telescope achieving first light in January 2009.
The observatory operates as part of the Global Oscillations Network Group, contributing to international solar research collaboration while offering monthly public tours through partnership with the Big Bear Valley Astronomical Society.
Guided tours are conducted on the second Thursday of each month from 1 PM to 2 PM, requiring advance online reservations due to limited capacity and specialized safety requirements for solar observation equipment.
The facility captured one of the most accurate photographs of the Sun ever taken on July 2, 2010, showcasing a sunspot with extraordinary clarity that was celebrated by National Geographic as a top space image.
