NOAA warning over Solar Flares

The National Oceanic and Atmospheric Administration (NOAA) predicts that a severe solar storm could cause disruptions to GPS systems, power grids, satellite and airline communications.

While activity returned to normal when solar winds calmed on Monday, August 8, another explosion on Tuesday, August 9 was the most significant flare of Solar Cycle 24.

In 2013, solar activity levels are expected to peak with the next solar maximum within the 11-year solar cycle.

This is why NOAA forecasted when space weather is coming our way. Coming up to the next solar maximum, we expect to see more storms from the Sun.

The NOAA said most solar flares will only cause minor problems, but some scientists believe that another such big event is now overdue.

In a huge solar storm back in 1859, telegraph offices worldwide were hit, some telegraph operators reported electric shocks and the telegraph systems malfunctioned.

The NOAA predicted four extreme solar emissions which could threaten the modern planet that is even more reliant on computer and satellite based systems.
