I have been informed that on December 4, 2022, APOD was a clue on a Washington Post Sunday Crossword Puzzle. Here is a link: https://www.washingtonpost.com/crosswor ... -birnholz/
The APOD clue was for 113 Down and read
"Org. with an Astronomy Picture of the Day site".
Cool! Thanks to those who informed us!
