HDEV Malfunction? (July / August 2019)

Strange to say, thanks to APOD (Astronomy Picture Of the Day) I learned about the existence of the High Definition Earth Viewing cameras aboard the I.S.S.! (must have been an APOD of just a few months ago). But... alas... there seems to be a malfunction up there (July 2019). During these few months of watching the daily HDEV images, I could see several less-known optical phenomena in earth's atmosphere (the Glory, the Cloudbow, etc...), and also bright twinkling solar reflections in meandering rivers, especially in South America. Another thing which caught my investigating eyes was the appearances of several tiny point-shaped solar reflections in the upper central part of Europe. I guess they were created by the sun shining on large surfaces of combined mirror-like solar panels (??). There's lots to see in these images, and I wonder if the malfunction of the HDEV is a permanent phenomenon? I hope it is not! By the way, a Fish-Eye camera aimed toward Earth's Nadir would give us spectacular images of the whole Earth! DannyJ.Caes (talk) 20:39, 27 July 2019 (UTC)
