In planning for a photo opportunity with either or both the International Space Station and an Iridium Satellite flare I use each of the 3 web sites displayed in the slideshow below in addition to the information provided by the Kindle App, ISS Detector Pro. If my Knidle is not available I go online to the NASA Spot the Station web site for important viewing information including where and when the ISS is visible, and the duration of its visibility. The link here takes you to where you choose a location. Once selected the sighting opportunities will be calculated for that location.
Another online resource is the SATVIEW web site. Your ISP will be detected and used to determine your general location like latitude, longitude, and timezone. This information is then used by the web site to calculate satellite visibilities and other data for your location. You may select from a list of satellites to track and then watch its orbital path on a larger Mercator projection type map of the Earth. Superimposed on top of this map is an animated graphic that shows the satellite from above in motion as it orbits the Earth’s surface below. Below these maps is a data stream display of location information, speed, altitude and so on, and is constantly updating.
The AstroViewer web site shows an animated graphic as if looking down from the ISS as it orbits above the Earth’s surface. It also displays a data stream of information about the ISS as well as the orbital path plotted on a world map. The ‘ground track’ shows the path the ISS is following and is updated every second. Clicking on the snapshot button opens a new browser window with a larger and more detailed graphic of what the ISS was orbiting above. Additionally you may get a visibility listing for a location similar to the list from the NASA web site.
This particular web site, AstroViewer, requires the use of Java and if you have heeded any of the cautionary reports about using Java then your computer should either not allow Java and subsequently not show the animated graphics, or you will be prompted to allow the use of Java.
