* 31st March - nearby satellites to your home lat long over the horizon that are sunlit are now shown in yellow. If your location is after sunset or before dawn you may be able to locate these visually by elevation and azimuth, depending on reflectivity and other factors. Thanks to @laurenlaufman for this idea.
Launch 22 (official launch 21 / March 11th) is added. 14th and 24th launch sats are not yet in Norad.
* 30th March - Data dumped for visibility now includes all satellites over 25 degree elevation plus a new column for whether or not the red line is drawn (cone of receiver). You can now do your own analysis by filtering for azimuth and elevation to determine number of satellites in view assuming a certain dish orientation
* 28th March - Folder icon downloads visibility data as a CSV if browser is left viewing 'home'. (work in progress). An hour of data is roughly representative of theoretical connection status at your latitude but with many uncertainties.
* 21st March - fixed bug where green home dot did not appear. Zooming in now gives elevation and azimuth to "in range" satellites. State boundaries now plotted.
Most preferences can be set (persistently stored) using the cog (settings) link at the top. You can increase performance by turning off rings, turning off ground station dots and filtering for active satellites.
Mouse: click hold and drag to move globe, zoom in with scroll wheel or two finger touch pad move. Zoom for more detail.
Mobile: use normal touch operations to move and zoom/unzoom globe
Circles show the approx area of usability with 45 degree max elevation
