Important Message about the Bobcat Fire:
All non-essential staff were evacuated from Mount Wilson on the morning of September 7th, 2020 because of the Bobcat Fire burning in the Angeles National Forest. As a result, the CHARA Array is currently closed, and we have suspended observations. We plan to reopen when staff can safely return to the mountain and when the smoke and ash clear. Current conditions can be monitored from the Mount Wilson HPWREN Cameras.
Important Message about COVID-19:
Night-time observations at the CHARA Array resumed on May 26, 2020. We are currently operating with a limited number of staff on site. All observations will be conducted remotely. Please see the Remote Observing page for more information on preparing for upcoming observing runs.
