Well, JPL looks OK, but Mount Wilson Observatory is next in the line of fire, so to speak.

Incident Overview

Structural protection crews are back in place on Mount Wilson today continuing preparation for its defense. While the mountain top is not yet out of harm's way, crews are more hopeful about its defense today after additional fuel break construction has been put in place.

The Station Fire is now estimated to be 121,762 acres. Good humidity recovery last night resulted in decreased fire activity. Winds will shift from the northeast to the southwest this afternoon and increase to 30 mph on the ridgetops whish is expected to increase fire activity later in the day. There is a possibility of afternoon thunderstorms over the San Gabriel Mountains that could result in strong downbursts of wind.

On the west flank of the fire crews manage sveral succesful burnout operations. Today crews will be working to secure these areas.

An additional fire camp to support fire operations has been set up at Central Park in Santa Clarita.

The Station Fire continues to burn within the Angeles National Forest and near surrounding foothill communities of La Canada-Flintridge, La Crescenta, Acton, Soledad Canyon, Pasadena and Glendale. The goals of the firefighters are to keep the fire west of Highway 39 and Angeles Crest Highway, east of Interstate 5, south of Highway 14, Pearblossom Highway, and Highway 138, and north of the foothill communities and the Angeles National Forest Boundary. Steep terrain, decadent old growth brush and hot dry weather are factors that drive fire activity. Firefighters are working to build fireline and protect structures within areas affected by the fire.

And here's the last picture received from Towercam before backburning operations took out the connection. Smoke is from protective backburning - NOT the main fire.

Readers with a good memory will recall that in 2003, bushfires near Canberra Australia overran and destroyed the Mount Stromlo Observatory:-
