With the sun currently approaching solar maximum, the most active period in the solar cycle, solar flares have become more common and powerful. This has led to some concerns about damage to satellites and electric power grids and it has also helped generate amazing and beautiful auroras.

The increased interest in “space weather” has also spiked interest in our free Space Weather Viewer iPhone app, which we developed for NASA back in November. We’ve had 107,528 downloads in the Apple App Store this month. The downloads peaked at 9,035 on March 13th although we have had more than 4,000 downloads each day this month.

Outreach efforts by our partners at Goddard Space Flight Center and the Sun-Earth Day 2011 events have also likely helped push the numbers upward.  You can download the Space Weather Viewer iPhone app in iTunes store. If you’re a developer you can download the source code for the app at Github, there’s more about this release in previous blog post, Source Released for the NASA Space Weather iPhone App.

The Android version of this app will be available next month.
