The most powerful solar flare of the year erupted from the sun today (April 11) sparking a temporary radio blackout on Earth, NASA officials say.
The solar flare occurred at 3:16 a.m. EDT (0716 GMT) and registered as a M6.5-class sun storm, a relatively mid-level flare on the scale of solar tempests. It coincided with an eruption of super-hot solar plasma known as a coronal mass ejection.
"This is the strongest flare seen so far in 2013," NASA spokeswoman Karen Fox explained in a statement. "Increased numbers of flares are quite common at the moment, since the sun’s normal 11-year cycle is ramping up toward solar maximum, which is expected in late 2013."
ASA’s Solar Dynamics Observatory captured this image of a powerful M6.5 class flare, the strongest of 2013 at the time, at 3:16 EDT on April 11, 2013. This image shows a combination of light in wavelengths of 131 and 171 Angstroms.
NASA’s sun-watching Solar Dynamics Observatory recorded a stunning video of the strongest solar flare of 2013, showing it extreme detail. The spacecraft is one of several space-based observatories keeping track of the sun’s solar weather events.
NASA officials dubbed today’s solar flare as a "spring fling" for the sun, which has been relatively calm as it heads into its peak activity period.
Today’s M-class solar flare was about 10 times weaker than X-class flares, which are the strongest flares the sun can unleash. M-class solar flares are the weakest solar events that can still trigger space weather effects near Earth, such as communications interruptions or spectacular northern lights displays.
The solar flare triggered a short-lived radio communications blackout on Earth that registered as an R2 event (on a scale of R1 to R5), according to space weather scales maintained NOAA, Fox added.
When aimed directly at Earth, major solar flares and coronal mass ejections can pose a threat to astronauts and satellites in orbit. They can interfere with GPS navigation and communications satellite signals in space, as well as impair power systems infrastructure on Earth.
Scary Times For California Farmers As Snowpack Hits Record Lows 2015-04-02 2:45
The water outlook in drought-racked California just got a lot worse: Snowpack levels across the entire Sierra Nevada are now the lowest in recorded history â€” just 6 percent of the long-term average. That shatters the previous low record on this date of 25 percent, set in 1977 and again last year.

The Expulsion and Extermination of Eastern European Germans: An Overview 2015-04-01 17:40 "Since the end of the war about 3,000,000 people, mostly women and children and overaged men, have been killed in eastern Germany and south-eastern Europe; about 15,000,000 people have been deported or had to flee from their homesteads and are on the road. About 25 per cent of these people, over 3,000,000 have died. About 4,000,000 men and women have ...
Your Smartphone Could be Tracking You Every 3 Minutes, Study Says 2015-04-01 2:24
Your apps want to know where you are
Smartphone apps regularly collect large amounts of data on usersâ€™ locations, sometimes as often as every three minutes, new research suggests.
Researchers at Carnegie Mellon University conducted a study where they asked 23 people to use their Android smartphones normally, and tracked location data requests from each device with specially designed software, the Wall ...
