On April 28, after 12.33, the Iberian Peninsula was subjected to a major blackout captured from space. Three satellites Nasa The interruption of the power supply was followed from their polar orbit, which lasted at several points Early morningAnd his gradual return. Sumi-NBP, NOAA-20 and NOAA-21 Spain and Portugal flew six times Between the dawn and dawn, the recording of a series of snapshots that document the evolution of the dark.
This is a clear night in the entire region that made it easy to get pictures, the European Space Agency explains in a statement (Isa), It released the snapshots on Monday. These are explaining Chronology and BlackBerry MapFrom the first wipe to the twilight time, the supply is almost fully restored.
Although it was recovered in most parts of the twilight time, some parts were in the dark for a long time. In Eastern Antolusia, the provinces of Almeria and Grenada show in the south of Spain Urban luminous loss Until the early morning, the ESA points out.
“Earth’s monitoring satellites are important to respond to events and emergency on our planet. On April 28, three satellites in the NASA polar orbit captured pictures of blackouts How the supply has been restored In Spain and Portugal, “the agency summarizes its X account.
Andalusia’s (IAA-CSIC) Institute of Astrophysics Analyst Alejantro Sanchez de Miwal explains the ESA pictures. “By exaggerating a series of satellites by exaggerating and using NASA’s night instructions, We can identify the big green points It appears suddenly and gradually fade. “
The green spots indicate The absence of lightWhites show areas with standard power supply. This distribution is compatible with the operational parts of the power companies and gradually returning to normalcy, adding to the scientist, and many ESA efforts to monitor light pollution from space.
Example the importance of the existence of April 28 Space Tracking Tools ESA says that in order to evaluate the complex infrastructure, prioritize repairs and improve an emergency response. Most Europeans live lightly under contaminated lights.
For example, the ESA contributes to the Night Watch program, which is a European Multosphere’s work that reads the night’s light emitter. “As cases like this blackout Install the gates For future surveillance organizations, “European company concludes.
