There has been another solar flare event and chances are it will trigger auroras in the polar regions. A huge sunspot region blasted an intense solar flare on Thursday which NASA classified as X.13.

The intensity of solar flares are classified in categories A, B, C, M and X - A being the weakest and X the strongest.

Solar flares are bursts of energy and they can impact radio communications, electric power grids, navigation signals while posing risks to spacecraft and astronauts. The latest eruption reportedly impacted communication bands across Africa, Europe and some Asian nations.

According to NASA, the flare peaked at 3:13 pm IST yesterday and the Solar Dynamics Observatory watched it happen.

Dr. Ryan French, a British solar astrophysicist said that this was the 25th largest flare seen this year. With the SDO, scientists observed that the flares were erupting from edges of the Sun on east and west. While the eruption region on the west will face away from Earth by the weekend, the solar east will face our planet, says Dr. French.

Just hours before the latest eruption, scientists noted M-class flare eruptions from two giant sunspots named AR 3811 and AR 3814. The National Oceanic and Atmospheric Administration (NOAA) said that it resulted in a moderate G3 level geomagnetic storm.

A geomagnetic storm is caused by the disturbance in Earth's magnetic field when charged solar particles expelled by an event called Coronal Mass Ejection (CME) interact with it. This phenomenon also triggers auroras in the polar regions and they are likely to be visible throughout the weekend.

According to NOAA's prediction, they will be visible in parts of Canada, Russia, Europe and several states in the U.S.
