Building of the observatory

The Big Bear Solar Observatory ( BBSO ) is a solar observatory north of Big Bear Lake in the mountains of San Bernardino County in the US state of California .

The observatory was built in 1969 by the California Institute of Technology on an artificial peninsula. Its largest telescope before 2009 was a 65 cm vacuum telescope, which was then replaced by a 1.6 meter telescope, the New Solar Telescope (NST) . First light recordings by NST were released in August 2010. The NST has adaptive optics and was the largest solar telescope until 2019 , then replaced by the Daniel K. Inouye Solar Telescope with a 4 m aperture. Furthermore, two smaller telescopes are operated at the Big Bear Solar Observatory, including an H-alpha telescope , the “New Full Disk H-alpha Telescope” and an additional instrument for exploring the earth's surface .
