Solar Flare

Any Communications expert worth their salt knows that Solar Weather affects how we communicate.  We know that this includes Solar flares, coronal mass ejections, high-speed solar wind, and solar energetic particles.  These are are all forms of solar activity or combined, Solar Weather or Solar Storm.

The most likely effects will take the form of things that are supported by satellite assets.  Most notably in our day to day lives this take the form of Global Positioning System (GPS), China’s BeiDou Navigation System, or Europe’s Galileo system.  When solar flares hit the ionosphere they immediately have detrimental effects upon communications and radio navigation.  These Solar energetic particles take anywhere from 20 minutes to several hours to reach Earth.

The reason this is getting so much attention is that we’re at one of the peaks of the Solar Cycle.  These cycles occur every 9-14 years and 2012 happens to be one of the expected peaks.

What this really means to the average individual is that there may be a slight (extremely slight) noticeable increase in GPS accuracy and time to acquire satellites may take longer.  There may be similar issues with dropped calls.  This is where it becomes hard to determine and differentiate what is really causing the problems the normal individual is experiencing.

Did your dropped call happen because you were shifting cell towers, walked into a dense building, did the other person have the issue and nothing was wrong on your end, the list goes on.  There are so many examples of other issues on Earth to worry about when you are enjoying that new 4G iPad 3 then Solar Flares.

My advice is to sit back and acknowledge that there are simply things that are going to cause problems with your navigation and communications devices.  Make sure you are always aware of how to accomplish what you’d like to do without these items.  Review the map and routes you’re taking before you simply follow every turn by turn direction of your GPS.
