AstroGadgets is a free Windows desktop program for amateur astronomers that gathers information from various astronomy websites, provides a concise display of essential information and provides pop-up, audible, email or SMS (text message) alerts for events such as International Space Station passes and Planetary KP Index levels (conditions favoring aurora).

This tool resides on your Windows desktop (sorry no Mac version) and provides quick access to the following information:

  • Current SOHO white light image of the sun with other bandwidths accessible via keyboard arrow keys
  • Sunrise/Sunset
  • Current lunar phase
  • Moonrise/Moonset
  • Astronomical twilight end/begin (when it is completely dark for astronomy purposes)
  • Current local weather conditions
  • Bright planet visibility
  • Clear Sky Chart
  • Clear Outside Forecast
  • NOAA 48 hour weather forecast
  • International Space Station passes
  • Planetary KP Index
  • Meteor Shower daily ZHR

You can position the program anywhere on your desktop by dragging it. To access the menus, use the right mouse button.
