Massive Solar flares as 11 year cycle is approaching its peak


The Sun erupted with a big solar flares, triggering prospective disruption to radio signals in the coming days and serving as a prelude to a period of heavy solar activity.

The intense bursts of energy this week were all "X-class" flares - the strongest type.
These are assigned a number which gives more information about their strength: An X2 is twice as intense as an X1, an X3 is three times as intense, and so on.

The first of the recent flares, which was given an X1.7 designation, appeared at 0317 BST on Monday 13 May. That was followed by an X2.8-class flare at 1709 BST on the same day and an intense X3.2-class flare at 0217 BST on Tuesday.

These flares - the strongest solar activity of 2013 - occurred in the space of just 24 hours.
According to the Space Weather website, a fourth, X1-class flare was unleashed at 0252 on Wednesday.

The radiation burst was the biggest in 2013 and "caused an radio power outage that has considering that gone away," Science World Report reported.

Scientists anticipate even more such solar flares this year, due to the fact that the Sun's 11-year task cycle is approaching its peak, expected to arrive in the closing months of 2013.

When solar flares appear, they do not always trigger CMEs but this one did, slinging one out of the Sun at more than 600 miles per second, according to Science World Report. That has actually researchers concerned about this specific flare because CMEs can potentially "trigger a space weather sensation called a geomagnetic storm, which takes place when they get in touch with the outside of the Earth's magnetic envelope, the magnetosphere, for a prolonged time period," according to NASA.

If that takes place, ground-based and orbiting electronics systems could be disrupted, affecting areas like GPS navigation, satellite interactions and broadcasting, flight, and ground-based radio signalling over cell networks.
