time for another guess the shadow contest

here's yet another mysterious shadow to wrap your brain around. it may be harder than the last one but should be guessable for the sharpest of shadow hunters. you others🤭 may prefer to focus on creativity and imagination and make up something.🤠 of course all replies are most welcome and will be rewarded with 20 ecency points, courtesy of mostly merciful @melinda010100.

what on earth is making this shadow??

or maybe it is not even on earth. at any rate the first correct guess and the most imaginative both get 1 HBD each. (i know, i know it was Hive before but Hive may be on the way back to the moon and beyond or maybe it's crashing so who knows how much it will be worth in a week. HBD is far more stable) creativity and humor may also be rewarded with a nomination to @pixresteemer and maybe even some more ecency points. please consider reading through the replies to see if somebody has already guessed your idea. if somebody beat you to it or if you can't fathom what the real object could possibly be then concoct something that will make us all smile. please don't just upvote this post. join in the fun and make a guess before 12:12 on 12.12.
