A fire at the Costa Sur power generation station in southwestern Puerto Rico shortly after 0100 UTC on 7 April caused wide-spread (but short-lived) power outages over the island. Imagery above shows the Day Night Band visible imagery (0.70 µm) from Suomi NPP, and a marked decrease in luminosity is apparent in the 07 April imagery. I05 infrared (11.45 µm) imagery on the right (all imagery is from the NASA Worldview site) shows few clouds over the island. The animations below show Day Night Band imagery alone from 6-8 April, and I05 Brightness Temperatures from 6-8 April 2022.
