Third Mid-Level Flare From New Sunspot: Nov. 5
November 6, 2014

On Nov. 5, 2014, the sun emitted a third mid-level flare from a region that rotated over the left limb of the sun on Nov. 3. The flare peaked at 10:46 p.m. EST.

This flare is classified as an M5.4-class flare.

Updates will be provided as needed, with imagery when available.
 


Second Mid-Level Flare From New Sunspot: Nov. 5                                                      November, 6, 2014

An active region on the sun emitted a mid-level solar flare, peaking at 4:47 a.m. EST on Nov. 5, 2014. This is the second mid-level flare from the same active region, labeled AR 12205, which rotated over the left limb of the sun on Nov. 3.

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.

To see how this event may affect Earth, please visit NOAA's Space Weather Prediction Center at http://spaceweather.gov, the U.S. government's official source for space weather forecasts, alerts, watches and warnings.

This flare is classified as an M7.9-class flare. M-class flares are a tenth the size of the most intense flares, the X-class flares. The number provides more information about its strength. An M2 is twice as intense as an M1, an M3 is three times as intense, etc.

Updates will be provided as needed.
 


 

NASA's SDO Sees a Mid-Level Solar Flare: Nov. 3                                                                     November 4, 2014

The sun emitted a mid-level solar flare, peaking at 5:40 p.m. EST on Nov. 3, 2014. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. 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.
