Graphic from GOES-16

In My Humble Opinion
1

At NOAA’s GOES-16, at what I am guessing to be about 43N and 114W I am seeing a persistent spot. Been there for about a week. What do you suppose might cause this?

All I see there is the outline of the Great Salt Lake. Not sure if that’s what you’re referring to. Does it go away if you press “M” to disable the map outlining?

Thanks.
