The sun released two major solar flares on Tuesday, March 6, 2012, as shown in the video below, taken by NASA‘s SDO (Solar Dynamics Observatory), which one of them noted to be the most powerful solar storm this year.

As noted at that day, both of the huge flares was classified as X-class storms, the strongest type of solar flares the sun can have, as one of them ranked as X5.4-class flare, which was followed by several weaker but still powerful sun storms.

Based on NASA solar flares ranking rules, there are five strength categories: A, B, C, M and X, with the A-class flares being the weakest sun storms, while the X-class events are the most powerful solar flares.

According to Space Weather Prediction Center, which is being operated by the National Weather Service (NWS), the X5.4-class solar flare, dubbed as the strongest solar flare yet for 2012, occurred at 7:02 p.m. EST on Tuesday; while the second one had a maximum strength of X1.3 and happened about an hour later.

Apparently, astronomer Tony Phillips of said that the huge X5.4 solar flare was said to have erupted from the giant active sunspot AR1429, which was also responsible for the major sun storm last Sunday.

“First-look data from Stereo-B are not sufficient to determine if the cloud is heading for Earth. Our best guess is ‘probably, yes, but not directly toward Earth. A glancing blow to our planet’s magnetosphere is possible on March 8th or 9th.” Mr. Phillips wrote on his website.
