Weather information

As part of our weather pages, we include a live image from the All-Sky-Camera positioned next to the GTC. Beyond showing the right Ascension and declination when placing the cursor in the image, we now show where the telescope is pointing currently, and added a wind-rose in the same coordinate system as the camera image. In the same display we now also show thumb-sized images taken from all-sky surveys of the area on the sky where the telescope is point. All this information is only visible to local NOT users, and this is often used by observers during the night. In the near future we will also indicate on the display what is the maximum allowed zenith distance when the wind-speed is too high. All this is to help observers to decide where is the best place to observe in case the weather conditions are not optimal.
