Los Angeles Times: Residents of rural communities in Los Angeles County are fighting to protect their view of the night sky. The county’s Department of Regional Planning has been asked to develop a rural lighting zoning ordinance. Possible approaches include shielding lights, turning them toward the ground, and switching them off at a reasonable hour. Lighting has been regulated in other areas, such as Flagstaff, Arizona, for decades. So foreign are the real night skies to Los Angeles residents that in 1994, after the Northridge earthquake jostled Angelenos awake at 4:31am and knocked out most of the power, the Griffith Observatory received many calls asking about “the strange sky they had seen after the earthquake,” said Ed Krupp, the observatory’s director.
