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 Global Positioning System GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours. This flare is classified as an M6 flare. M-class flares are the weakest flares that can still cause some space weather effects near Earth.
They can cause brief radio blackouts at the poles. It has since subsided. Increased numbers of flares are quite common at the moment, since the sun's normal year activity cycle is ramping up toward solar maximum, which is expected in The eruption, called a coronal mass ejection, caused aurora near Earth on September 3. Part of the filament seems to break away, but its basic length and shape seem to have remained mostly intact. On July 28, , the sun emitted a mid-level flare, categorized as an M6.
The flare is visible here in the lower left-hand side, coming from an active region on the sun named AR This im This flare is classified as a M6. M-class flares are the weakest flares that can still cause some space weather effects near Earth. Since arriving, it has let loose two M-class flares on March 2 and 4 and one X1 class flare this morning.
This increased solar activity is a normal byproduct as the sun approaches solar max. Additional hits will occur over the weekend. This was an X2. Though not Earth directed, we may experience radio and communications blackouts.
They were not disappointed. No Earth directed affects are expected. The Sun unleashed an M-2 solar flare, an S-1 radiation storm and a spectacular coronal mass ejection in the early hours of June 7, Increased aurora activity because of the Aug.

The sun unleashed two massive X-class solar flares on March 6, The flare erupted from the giant active sunspot AR The massive sunspot region AR has been particularly active since it emerged on March 2, The flare appears as the bright spot in the upper left. This still from a NASA video shows the sun as it unleashed a major solar flare overnight on March 4 and 5,
