Satellite Predictions and Visibility

NASA Skywatch NASA SkyWatch is a web-based Java application that provides sky watchers worldwide with a picture of when and where the International Space Station, the space shuttle and other spacecraft can be seen with the unaided eye as they pass overhead. Heavens Above Provides all the information you need to observe satellites such as the International Space Station and the Space Shuttle, spectacular events such as the dazzlingly bright flares from Iridium satellites as well as a wealth of other spaceflight and astronomical information.

Online Skymaps and Charts

Your Sky An interactive planetarium run by Fourmilab. You can produce maps for any time and date, viewpoint, and observing location. If you enter the orbital elements of an asteroid or comet, Your Sky will compute its current position and plot it on the map. Each map is accompanied by an ephemeris for the Sun, Moon, planets, and any tracked asteroid or comet. A control panel permits customisation of which objects are plotted, limiting magnitudes, colour scheme, image size, and other parameters. Heavens Above Provides a range of charts and information, including sky charts for your loacation (which you'll have to specify).
