SkyWeek Plus is the new, enhanced version of SkyWeek — a day-by-day calendar of events to observe in the changing night sky. SkyWeek Plus takes the guesswork out of finding the best celestial sights. It’s a daily diary of the most interesting astronomical happenings. It comes with an interactive sky chart you can customize for your location. 
 
You can synch SkyWeek Plus with your calendar so you’ll never forget about an important sky event. Plus, SkyWeek Plus users will receive special alerts if any unexpected events such as solar flares, unknown asteroids, or stellar explosions suddenly appear.
