Sun Releases Strongest Flare Recorded Since 2006

Meanwhile, NASA managed to capture spectacular images of the two significant solar flares emitted earlier this week on the Sun. The first solar flare was seen at 5:10 a.m. EDT while the second, larger flare, peaked at 8:02 a.m. EDT.

The space agency said the solar flares were accompanied by a coronal mass ejection (CME) and this could have an impact on technology. The larger of the two was classified as X9.3, the strongest since an X17 flare in 2005.

Both the intense flares came from came from Sun's active region called AR 2673, which continues to unleash solar flares even today. The Solar flares are powerful bursts of radiation. They often follow solar flares, and can cause geomagnetic storms. This is a phase when such eruptions on the sun are increasingly rare, but history has shown that they can nonetheless be intense. M-class flares are a tenth the size of the most intense flares, the X-class flares. The radio black out from this particular flare is already passed. That's because the sun is now approaching its solar minimum, which is the bottom end of its 11-year activity cycle in which events like solar flares and CMEs should be an extremely rare occurrence. Scientists also found rotation rate of the sun has changed.

Updates will be provided as needed. The region has been moving across the face of the sun since March 2, and will soon rotate out of Earth view.

The way limb darkening works is that when you look at the center of the sun, you have an unobstructed view of the warm and bright base of the photosphere, but as you start to look towards the edges, the sun's curvature makes it so that you can only see the upper layers of the photosphere.

According to National Institute of Polar Research associate professor Ryuho Kataoka, there was also a smaller solar flare at about 5 a.m. on September 5, Japan time.

The particles have no impact on the human body, but past major flares have caused Global Positioning System trouble, damaged satellites and triggered blackouts, prompting the warning from the National Institute of Information and Communications Technology (NICT).
