Light pollution has pushed skilled astronomers to site their observatories on distant islands and mountaintops, while taking beginner astronomers—and their children—of weak stars and galaxies lost in the glare. Much of modern day astronomy depends on spectroscopy, where we should be able to find light at the particular wavelengths equivalent to numerous elements. If we all work with each other, upcoming generations can recover some of the pleasures of viewing in the dark.
When a massive power outage struck southern California in the 1990s, Los Angeles residents reportedly called 911 to express alarm about strange clouds hovering overhead; they were seeing the Milky Way for the first time. Thousands of Southern California residents were without power Monday night as dangerously hot weather prompted an all-time high for electricity demand. More than 6,000 Los Angeles Department of Water and Power customers were without power in the service area Monday night, according to spokeswoman Mary Anne Pierson.
Southern California Edison had also reported some outages in a number of its service area, including Beverly Hills, Pacific Palisades, Inglewood and Chino Hills. Most of the power outages were caused by the sweltering heat combined with high electricity usage. Earlier in the day, LADWP had advised customers to conserve energy in an effort to reduce the strain on the power grid and minimize the risk of potential power outages. To reduce the stress on the grid, residents have been advised to adjust air conditioning thermostats to 78 degrees between 11 a.m.
Customers were also urged to limit use of major appliances -- such as washing machines, dishwashers and vacuum cleaners -- during daytime hours. City facilities, such as senior citizen centers, recreation and parks facilities and libraries, may be used as cooling centers, the L.A. Temperatures between 100 and 110 degrees were forecast in many areas from late morning through the evening, with even the beaches -- typically viewed as a hot-weather escape -- facing temperatures of 90 to 100 degrees. Temperatures were set to decrease beginning Wednesday, but humidity was expected to increase due to precipitation caused by Odile.

But the LADWP’s circuits were overloaded by the increased power demand later on Saturday as temperatures rose, and thousands lost power again.
Other outages Saturday were reported by Southern California Edison on its Web site, including 1,676 customers in Los Angeles County that were without power in areas including Inglewood, Long Beach, Lynwood, Baldwin Park and Lawndale. SCE also reported 80 customers in Orange County were without power.
Traffic heading to Los Angeles International Airport was heavily delayed after a power outage on Wednesday, Aug. A brief power outage at Los Angeles International Airport Wednesday night caused major traffic delays. Residents in Glassell Park have the highest number of power outages caused by the windstorm in Los Angeles, the Department of Water and Power said. There were also outages in many other parts of the city, including 1,400 in Venice, 4,200 in Hollywood and 5,000 in Los Feliz.
Power has already been restored for nearly 150,000 of 1.4 million customers, officials said.

Low-pressure sodium lamps emit light at only a few distinct wavelengths, making the rest of the range free of polluting light. LADWP and SCE crews were continuing to work on restoring electricity to all other affected residents, but it was not immediately clear how long the outages would last. And it’s really just air conditioners that are running continuously,” said Joe Ramallo with LADWP.
Tuesday by the weather service for much of Los Angeles, Orange, Riverside, San Bernardino and Ventura counties. Friday, there were 11,800 homes without power in Glassell Park, followed by Cypress Park, where 10,200 were still in the dark.
Highland Park had nearly 10,000 without power, and Boyle Heights had 3,400, according to the DWP.

Other actions include placing motion sensors on the security lights that, in so many situations, overflow personal yards all night; this actually improves protection while saving on energy bills. They said that crews were able to restore power to a water system and that water levels had returned to normal. Officials said that there were 67,000 total without power and that 134 work crews had spread out across the city to tackle 500 outages. These lights are also incredibly energy-efficient, making them the most cost-effective form of street lighting.
Friday night, according to Southern California Edison.Manhole Covers Explode in Long BeachA City of Long Beach statement said network retests Thursday night and early Friday were unsuccessful, and gave no time for a likely restoration. 17, 2015)A series of power outages that have struck Long Beach within about one month have generated new concern among residents who were left in the dark.Officials will be holding a town hall meeting Saturday to discuss the recent outages, which have affected the downtown, East side and nearby areas.
15 affecting more than 20,800 customers in the East side of Long Beach and the Traffic Circle area.
People here are panicking because they don't know what to do," a Long Beach resident said. The outage was resolved within a few hours, according to SCE's online outage map.The city's most notable, recent outage occurred July 15 after an underground electrical fire sent exploding manhole covers flying into the air. The outage lasted about three days, leaving about 4,800 customers without power during its peak.Long Beach Power Restored After Three Day OutageSCE officials said the outages that occurred in the downtown area last month were probably not connected to the recent outages in East Long Beach, but they are investigating the incidents as a whole. SCE said the recent outages were likely heat related.Resident will be giving feedback to SCE and PUC officials at the town hall meeting. Edison will also share what it has learned so far in its investigation into the outages.Manhole Covers Explode in Long BeachThe town hall meeting will be held Aug.
