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.

Fantastic weekly sky events app, with minor flaws

I love checking this app every now and then to see what's "up." There are usually several events listed, from purely naked eye to occasional small telescope challenges.

But the real gem is the sky chart that opens when you tap an event. Yes, it shows you the selected event at your location. But you can go backwards and forwards in time (in any step from seconds, minutes, hours, etc) - great for occultations!

But it gets better: pinch and zoom can take you from the whole sky to maybe 5 arcsec or less! Again, great for timing occultations, and also for seeing planet discs. Lots of Messier and other common objects are marked and appear if you zoom sufficiently (but most are not graphically displayed - this isn't Celestia).

So what's missing? My biggest gripe is that the week's events are followed by a text description of the planets, but I would really like a link to the planet in the sky chart, especially when hunting for Uranus and Neptune. [6/2018 UPDATE - I saw Uranus in the app!]

I'd also like to see major moons. Once I saw it depict Galilean shadows on Jupiter but not the actual moons. I'm not sure if the shadows are a regular thing or just s special event. [6/2018 UPDATE - now it shows the moons & shadows anytime!]

Last, the weekly list updates all at once, on Sunday I believe. I would love to see more upcoming events, as I have missed some I'd have liked to see because I did not check in time. I know the paid version lets you add events to your calendar, but this must be done manually.

Not bad, but always begging for money.
