To commemorate the 1st anniversary of the discovery of Neptune (in Neptunian years) Hubble released a series of images recorded on June 25-26 2011 depicting the entire cloud surface of the planet over one rotation. Neptune HST 2011

I created a simple cylindrical projection skin using these images that can be used in some planetary programs (such as WinJUPOS) using these images. Feel free to use the attached image if you'd like.

Thanks!

by the way, all the clouds are in their proper positions; the map has 0-degrees at left. It's a simple matter to change it to put 180 at left, for those who prefer that convention. I wonder if the team shot red data, rather than near-IR. I'd like to make a "true" color skin someday.

The "green" color is apparently F631N (red) filter so that answers your question - although it's not exactly an ideal color filter as it's narrowband. The question then becomes whether they actually shot something in the green range and based on my experience with previous Hubble obs, I don't think so. For reference, here's one older observation with WFC3 which did take green and the other two filters are the same.
