SkySafari Shows Solar System Spectacles!

Total Solar Eclipse followed two weeks later by a Total Lunar Eclipse.

Starting Friday, March 20th, two spectacular solar system events will take place.

Total Solar Eclipse

This eclipse is not visible from North America but can be seen as a partial eclipse in Europe, Africa and eastern Asia. The path of totality runs through the North Atlantic Ocean and includes Svalbard (Norway) and the Faroe Islands. For people living outside the area where the eclipse will be visible, SkySafari allows you to see it happen.

Anyone wishing to view the eclipse live should view it through special solar observing filters or by projecting the Sun's image. Don't ever stare directly at the Sun, even with sunglasses, and especially not through a telescope!

To simulate the March 20th total solar eclipse:

Tap Settings -> Location and enter the following:

Name: Faroe Islands
Latitude: 62.17064 N
Longitude: 7.0103 W
Elevation: 1
Time Zone: 0

Tap Settings -> Date & Time and set the time to 8:30 AM on March 20th, 2015.
Tap Search and enter "Sun" (or select Sun from the list of Sun & Planets).
Tap Center at the bottom of the info screen about the Sun.
Tap Time to show animation controls.
Tap the Run button (right arrow) to flow time forward at one minute per step. You can also stop time flow and use the Step Time button (second to right arrow) to step through the eclipse.

You can also see what the eclipse will look like from you location by choosing "Current Location" in the Location settings and following steps 2-7 with the time being offset by your time zone.

Total Lunar Eclipse

A total lunar eclipse will occur on April 4th, 2015. This is where the Earth's shadow falls upon the face of the Moon. Whether you can see it from your location depends solely on whether the Moon is up in the sky when it occurs.

To simulate the total lunar eclipse:

Tap Settings -> Location and tap on "Use Current Location".
Tap Settings -> Date & Time and set the time to 6 AM on April 4th, 2015. This is the time for Denver, CO (MDT). You might have to adjust it for your time zone (8 AM EDT; 7 AM CDT; 6 AM MDT; 5 AM PDT).
Tap Search and enter "Moon" (or select Moon from the list of Moons).
Tap Center at the bottom of the info screen about the Moon. You should now be able to see if the Moon is above or below the horizon.
Tap-and-hold the + button at bottom right on the sky chart to zoom in on the Moon.
Tap Time to show animation controls.
Tap the Run button (right arrow) to flow time forward at one minute per step. You can also stop time flow and use the Step Time button (second to right arrow) to step through the eclipse.
If you have SkySafari Plus or Pro you can turn on "Earth and Moon Shadow Circles" to see how the Moon passes through the Earth's shadow.

The best mobile astronomy app keeps getting better

Now, SkySafari 4 makes the best mobile astronomy app even better. We've reimagined its interface for iOS and Android, with fully redesigned telescope controls.

The star and solar system object databases have been rebuilt, with 80% more stars in the Pro version.

SkySafari 4 is a complete reinvention of the app that adds the features our users have asked for most often during the past two years. SkySafari 4 isn't just a makeover - it's an overhaul.

SkySafari 4 comes in three versions - Basic, Plus, and Pro. All three versions require iOS 7+ or Android version 2.2+.

SkySafari 4 is also available for Mac OSX 10.6.8+ in the Mac App Store.
