Hello everyone im fairly new here.. i have some images id like to share and get your thoughts about i did bring them to the attention of a space agency group here in canada it was several years ago now so im not recollecting the name of who i had contacted.. Any how they told me it was dust on the lense what do you think ? or perhaps someone here has knowledge of what it is i observed in these photos.. I use to check the stereo ahead images every day cause i found them really fascinating plus it would upload images straight from the sattelite to the website and so you could get real time images several minutes apart, and every once in awhile you'd find these images with these anomalies i would call them.. and the more interesting thing i found is that when these anomalies would appear they would only stay up on the site for maybe several hours only to be removed by whoever the administrator is maintaining the database.   Screenshot_20170901-221636.png
