SkyWeek is the new, interactive, mobile version of Sky & Telescope magazine’s super-popular “This Week’s Sky at a Glance” web page — a day-by-day calendar of events to observe in the changing night sky. “This Week’s Sky at a Glance” has been Sky & Telescope’s most popular online offering for 21 years. The S&T SkyWeek application gives you access to the content and interactive features described below.

SkyWeek now adds interactive, custom sky maps that are automatically set for your location (not the static version’s compromise for the center of North America). And starting from the sky scene that’s displayed, you can pan all around your heavens, change the scene to other times and dates, and zoom in or out.

• All major sky events: eclipses, conjunctions, good meteor showers — miss nothing!

• Zoomable constellation charts: pan around your whole sky, and change to any time or date!

• Automatically customized to your location worldwide.

• Links to more info.

Whether you’re a newbie skywatcher or an experienced amateur astronomer, SkyWeek will become your handy, everyday guide to what’s up.
