Day Night Band imagery of Idalia and Franklin
NOAA-20 overflew Hurricanes Franklin and Idalia shortly after 0700 UTC on 30 August 2023. Ample lunar illumination (the Full Moon occurs on 30 August) meant the Day Night Band yielded very sharp imagery, as shown above. This data was downloaded at the CIMSS Direct Broadcast antenna and processed with CSPP software, yielding the georeferenced image above (more imagery from this overpass is available here; ATMS imagery from the pass is here; both image repositories will be purged in a week). Idalia made landfall along the central Florida coast at about 1145 UTC, four+ hours after the imagery above was captured. Franklin is a larger storm with a much larger eye compared to Idalia.
