ABC7 (KABC), the ABC affiliate station in Los Angeles, lost its over-the-air signal Friday morning as the Eaton Fire burned near the Mount Wilson observatory and communication towers in the Angeles National Forest.

The Eaton Fire burning through the hillsides and mountains above Pasadena is now approaching the Mount Wilson Observatory, with potential implications for both the historic structures and emergency communications during the ongoing wildfire siege devastating Los Angeles.

The key NASA center remains under a mandatory evacuation order, but officials say both it and Mount Wilson are protected for now.
