Don Fregulia, an operations section chief for the California Department of Forestry and Fire Protection, which has joined in the Eaton fire response, said that efforts to protect Mt. Wilson had proved successful and he expected that to remain the case.

The blaze threatened the observatory and communications infrastructure at the peak. Later, an observatory official said it appeared to be under control.

The Eaton Fire that started in the foothills northeast of Los Angeles flared up Thursday morning near Mount Wilson.
