Access to data at IRSA recently has moved to requiring HTTPS URLs. This has broken SkyView’s access to the WISE and 2MASS surveys. We have just updated the URLs in the current version of SkyView to re-enable access to these popular surveys.
Note that since this bypassed our regular release procedures users of SkyView in a Jar may wish to delete any wise.xml.gz or 2mass.xml.gz files in their skycache directories to ensure that they get the latest survey description files with the updated URLs.
