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.

I used to use this app 5 to 7 days a week

UPDATE: This once-great app has been abandoned by Sky & Telescope magazine and died of neglect.

Without notice or explanation, they ran away from its upkeep and now it is it is no more. It has passed on. It’s shuffled off this mortal coil and ceased to function. It is an ex-app.

The pure pleasure of looking informedly at the night sky used to be the point of this moribund app (and of amateur astronomy.)

It used to be terrific for naked eye astronomy and for binocular viewing, too. They used to tip you off to seasonal formations, planetary conjunctions, asterisms, comets (when they were easily visible), meteor showers, etc.

But now it does nothing at all but take up space and frustrate.

The writing used to be warm, accessible, informative & brief. The diagrams were once very useful.

This free version is just as dead as the pay one (the difference is the pay version used to link to your calendar.)

Especially for a beginner or intermediate amateur astronomer, this used to help make looking at the night sky a fun thing to do and share with friends.

But not any more. Because it’s dead.

Dead App...No Word from Developers

This app was really helpful to me as a science teacher. Obviously, the developers have given up on it as it no longer even opens properly. A word about when or why would have been considerate, and a decent business move. I don’t know how closely tied the app actually was to Sky and Telescope magazine, but my frustration with the app is the reason I won’t be renewing my subscription.

App Ran It’s Course

But I couldn’t bear to give it a poor review. It doesn’t work anymore. But when it did, it was the best for amateur astronomers. Mapped out the entire night sky for you. The tips, what to look for, astronomical occurrences. RIP :,(
