> Description of problem: I just noticed a "fuzziness" or reduced resolution of 
> downloading the 0.47 um GOES 16 17 vis images. It used to be served up at 
> 0.5km, but now appears to be 1km resolution. The higher spatial time and 
> space resolution of 5min to 1min and 0.5 km is important for analyzing 
> development of small scale cloud development.

I believe this is the change to save some bandwidth, no mistake.
