A powerful solar surge caused the emission of a giant plasma stream and provoked radio interference in the southern part of the Pacific. As a result of the explosion that occurred in the Sun, in Australia and Southeast Asia short-term Radio Plugs.
The surge occurred due to the unstable sunlight AR3575 and was recorded on Monday, February 5, at 20:30 Eastern American time (01:30 GMT February 6), reaching a peak at 22:15 EST (03:15 GMT) . According to Keith Strong, a physicist at Sunny Physics who shared the details of the flash on the X platform, the event was accompanied by the release of the coronal mass (CME) – a significant liberation of plasma and the magnetic field of the Sun. Although this CME probably will not reach the Earth because of its southern location in the sun, it can pass by our planet, without causing geomagnetic storms that could harm the satellites in the orbit of the Earth, but would pleased hunters for the northern lights.
Class M flash caused extensive radio interference due to a strong flow of x-rays and ultraviolet radiation, which reached the Earth about eight minutes after the explosion and ionized the upper layer of the Earth – the thermalmosphere. As a result, in the illuminated part of the Earth, in particular in Australia and Southeast Asia, short-term radio black spots occurred, touching the radio communications at frequencies below 30 MHz.
Sun outbreaks are classified in size in alphabetical order: from the most powerful X-class to the least significant A-class. The recent flash was classified as M4.2. Exciting images and video of the solar flash were made by the NASA – Solar Dynamics Observatori space observatory, which continuously observes the sun in different wavelengths.
According to the forecasts of the National Ocean and Atmospheric Administration (Noaa), even more solar activity can occur in the coming days, since another unstable sunny spot of the region 3576 appears in the field of view, increasing the likelihood of class M and possibly class X.
