Sun Continues to Emit Solar Flares:-

The sun is currently in an active phase of its 11-year solar cycle.After emitting its first significant solar flares since June 2013 earlier in the week, the sun continued to produce mid-level and significant solar flares on Oct. 27 and Oct. 28, 2013.

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however when intense enough they can disturb the atmosphere in the layer where GPS and communications signals travel.

One of the larger flares was classified as an X1.0 flare, which peaked at 10:03 p.m.An X2 is twice as intense than an X1, an X3 is three times as intense, etc.It was discovered in 1843.

The solar flare activity has been travel With coronal mass ejections or CMEs,that can reach on Earth one to three days later.These particles cannot travel through the atmosphere and affect electronic systems in satellites and on the surface of the earth.CMEs can cause a space weather phenomenon called a geomagnetic storm and also cause aurora.Minor storming at very high latitudes will be possible if the incoming plasma cloud sweeps past Earth. Be on the lookout for visible aurora at very high latitudes.
