The image taken by TEMPEST-D (Temporal Experiment for Storms and Tropical Systems Demonstration) captures Florence over the Atlantic Ocean, revealing the eye of the storm surrounded by towering, intense rain bands. The green areas highlight the extent of the rain being produced by the storm, with the most intense rain shown in yellow and red. The TEMPEST-D data is contrasted with a visible image of Florence that shows the familiar cyclone-shaped clouds of the storm but doesn't reveal what's inside.

TEMPEST-D's mission is to test new, low-cost technology that could be used in the future to gather more weather data and help researchers better understand storms. The level of detail in the small-satellite image is similar to what existing weather satellites produce.
