EMail Alerts for Astronomical Events

CalSKY® was founded in 1991 by Arnold Barmettler to offer amateur astronomers a new way to plan their observing sessions. After you set up a profile, you select the events for which you want alerts. Each email alert is very informative and well formatted. Iridium flares, other satellites, comets, asteroids, and more are among the astronomical events you can choose to be alerted of.
