Most observatories plan their upcoming observations at least several weeks in advance. There are discussions ongoing to have such planning data published not only via Web pages, as currently, but also in a form that could be easily parsed by software.

Once that were available it would be interesting, especially for multi-wavelength campaigns to have a time-filtered view of theoretical footprints from observatories participicating in such a scheme. Note that this might require a generalisation as it is not clear yet how detailed such planning data would be, when published (e.g., does it precise the spacecraft rotation?).

This is a long-term idea, for the time when such interfaces exist.

Hi! Hope you're well! For the past few days I have been having an issue wherein Hubble and Webb imagery do not load. The frame and opacity slider appear, but that's it. Everything else, including Euclid imagery, is working normally. I've tried Firefox and Edge on my desktop and phone, as well as trying cable and mobile internet. When the image URLs are copied into a new tab, they load just fine. Any ideas as to what's going on? Thanks!

Dear whom it may concern, I just found out that there might be a bug in querying target by using different form of coordinates. For example, if I use the name of NGC291 or sexagesimal coordiante of 00:53:29.931-08:46:03.48, ESASky shows correct image of the target. However, if I use the decimal coordiante of 13.374713 -08.767633, ESASky shows incorrect field without target in the FOV. Could you check it please? Thanks~

Just a nit-pick, but currently if you outzoom far enough, you will see that you're looking at a sphere from the outside. For me it's rather confusing, night sky is not a planet, would be good to change the perspective, the further you outzoom, the winder your field of view should be. That's basically how all of the other astronomy/observatory applications work.

ESA Sky could really use an option to embed the map into a website. Preferably just generating iFrame to the current view with some options (similar to the Google Maps) as it's by far most user-friendly version.

Examples:

• Google Maps
• Open Street Map

Allow an instance of ESASky to be slaved to another instance of ESASky, such that if the user move the view, or change FOV of the 'master' instance the slaved instance should change acccordingly. This should be implemented in such a way as to be compatible with other ESA archives using the underlying technology, i.e. ESASky controlling EuclidSky, and vice versa

It would be useful to to be able to tag (label) the cursor position with a label when ESASky is opened via a URL in a similar way that positions can be tagged in the full version of Aladin.

The image shows the result in Aladin (full) - text is rather small but hopefully the idea is clear.

If implimented in addition to being able to acheive this via the URL it ought to be in the Python API as well.

Example: 12 12 12  -00 36 00 is converted to 12 12 12  +00 36 00 (reported by ATalavera)

Another suggestion from the teachers at the ESTEC workshop in November 2017: The possibility to mark a box or circle in the sky to select a region of interest to be displayed. 

Allow to change size and color of the symbols, like Alain does, to compare more easily catalogues like XMM, Chandra and slew, the 3 with similar color and size
