I was able to confirm this on my processing. The 1105Z files are cut off. I saw the same incomplete image on IR and WV. https://vietorweather.net/cgi-bin/wxp/satplot?if=sat_vis_g16f&ge=1000x700&cof=sat_vis16.cfl&cu=20240819_1105&pd=goese&com=lgray I checked many of the images on the 10 minute intervals and they're all complete. It's just the oddball one at 1105Z. Also, the glitch doesn't appear to be on a tile boundary. Dan.
