While the majority of the scene was lit by airglow from the mesosphere or by side-lighting from the city lights below, there were no obvious mesospheric waves from Hurricane Laura. This could be due to the fact that they were washed out due to the city lights. One other thing to note is a lightning streak within some of the convection in the Gulf of Mexico.<\/p>\n<p><a href=\"https:\/\/www.ssec.wisc.edu\/jpss-sdoc\/wp-content\/uploads\/sites\/29\/2020\/08\/DNB_NPP_072820_0751_1E-9_Laura_labels.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-3690\" src=\"https:\/\/www.ssec.wisc.edu\/jpss-sdoc\/wp-content\/uploads\/sites\/29\/2020\/08\/DNB_NPP_072820_0751_1E-9_Laura_labels-300x162.png\" alt=\"\" width=\"300\" height=\"162\" srcset=\"https:\/\/www.ssec.wisc.edu\/jpss-sdoc\/wp-content\/uploads\/sites\/29\/2020\/08\/DNB_NPP_072820_0751_1E-9_Laura_labels-300x162.png 300w, https:\/\/www.ssec.wisc.edu\/jpss-sdoc\/wp-content\/uploads\/sites\/29\/2020\/08\/DNB_NPP_072820_0751_1E-9_Laura_labels-1024x553.png 1024w, https:\/\/www.ssec.wisc.edu\/jpss-sdoc\/wp-content\/uploads\/sites\/29\/2020\/08\/DNB_NPP_072820_0751_1E-9_Laura_labels-768x415.png 768w, https:\/\/www.ssec.wisc.edu\/jpss-sdoc\/wp-content\/uploads\/sites\/29\/2020\/08\/DNB_NPP_072820_0751_1E-9_Laura_labels.png 1264w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>Speaking of lights and power outages, it is important to note not to draw any information about areas of outages from the imagery, given that most of the region was obscured by cloud.
